There are various types of sand, each being suitable for its own specific building, construction or landscaping use. If the soil under a building is not stable, the foundation of the building could crack, sink, or worse–the building could fall! Due to the fact that beach sand is collected from coastal regions, it does contain the afore mentioned salts that absorb atmospheric moisture and cause damp issues. Dune sand from the Gobi Desert, Mongolia 3. 2. A lot of guys here do rendering using building sand with a shovel full of sharp (screeding sand) in the mix. river sand) this sand-type is normally collected from the beds and banks of rivers or from around more inland water sources as, again, the presence of salts and other organic matter needs to be kept to a minimum to ensure that atmospheric moisture is not absorbed that could then cause damp issues. Sharp sand is commonly used when laying paving courses, such as driveways, paths and patios. Such as General criteria and Engineering criteria. Pit sand consists of sharp, angular and rough grains. We use this sand mainly for plastering purpose. Soil tests for construction of buildings or any structure is the first step in construction planning to understand the suitability of soil for proposed construction work. There are three main types of sand used in building and DIY and all have specific uses. (adsbygoogle = window.adsbygoogle || []).push({}); Feldspar commonly found in the earths crust and in a great deal of sand. As it is aimed as a direct replacement for river sand, it’s grains are of a similar size and shape. There are several different types of mortar that are used for various structures. With this in mind, sand should be treated as a precious resource and wastage kept to a minimum, not only to preserve the sand itself, but to also minimize the environmental impact that goes with having to supply billions of tonnes of sand globally. In the construction industry, you’ll hear of two main types of sand. As we briefly mentioned above, sand is arguably one of the most used materials in the building trade. Clay and water act as a bonding material to give strength. It has also high strength at high temperature which make it most useful material in mould manufacturing. Which types of sand should I use for concrete? A typical mortar joint formed when laying bricks and blocks. Now that you know all about the different types of sand and what type should be used for a given DIY or construction job, all you need to do now is get on with your chosen project. Required fields are marked *. The grain size of this type of sand is between 1.0 mm to 2.0 mm. We have highlighted them below and their recent prices. Types of Moulding Sand: According to the use, moulding sand may be classified as below: 1. Given its importance, how would you determine a good quality and the best type of sand used for building a house?

Very informative, thank you and keep it up. The sand which is passing through the 3.175 mm sieve is called coarse sand. Red sand typically contains higher levels of iron-oxide. Construction sand and gravel options range from the tiniest particles to large pieces of rock. In terms of the grains, unlike the course sharp and angular grains that make up sharp sand, the grains found in builders sand are much more rounded and smoothed off. One of the other key constituents of sand is Feldspar. When this happens, sand need to be sourced from another supplier or location where it may be of a slightly different colour, hence the difference. eval(ez_write_tag([[250,250],'diydoctor_org_uk-under_first_paragraph','ezslot_7',661,'0','0']));Don't want to do this job yourself?

Mortar is generally comprised of sand, lime or cement and water. On some occasions the available sand may also be a reddish colour. There are different methods for testing of sand quality at construction site for concrete construction. There are different types of sand used in various parts of a building project. In summary, builders sand should be used for: Builders sand or river sand used for plastering, mortar and masonry and laying bricks and blocks. For this reason, all sand used should be clean and free from clay, salts and any other impurities. The type of superstructure. Due to its superior binding quality, it is widely used in civil construction. But unlike gravel, crushed stone sand is a natural but commercially created resource that is made from crushed minerals, such as granite or limestone. It is used for bricklaying mortar, building foundations, for paving slabs, wall rendering. The quartz itself (otherwise known as silicon dioxide) is formed when oxygen combines with silicon. If you have done any concreting in the past or had to mix any mortar to lay bricks or blocks you will almost certainly have had to purchase some sand from a builders merchant or DIY shed. This is not only confusing to DIY newbies but can also be equally as confusing to the professionals! SAND Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. Next, it’s a waiting game! Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich dissolution series. Because they don’t make any sense. Based on where the sand is collected from, the Natural sand can be the following types: This sand is collected from the ground by digging a pit. When choosing between the several different foundation options, you need to consider two important factors: The type of building you want to erect, and The type of land you […] Sand to be used for mortar, as used for brick-laying etc has less of the large grit in it. As the grains are smaller and smoother, this results in a much smoother overall finish hence the reason builders sand is used in screeding and plastering applications. Pit sand is coarse type sand (I’ll discuss coarse sand later in this post). With the above in mind and the fact that steel is widely used in the building industry, I’m sure you can see why this type of sand needs to be kept well away from any structural steel as it will cause it to corrode in a relatively short space of time. Design of the foundation is based on soil test report of construction site. On a comparative level, artificial sand is a very close match to building sand mostly because building sand tends to be more widely used than any of the other types. The stones used for building construction should be hard, durable, tough, and should be free from weathered soft patches of material, cracks, and other defects that are responsible for […] If the grain size of the sand between 0.25mm to 0.50mm that is the medium sand. Structure: Homogenous, inter-stratified, heterogeneous, or weathered. The other type of sand is sharp sand. We discuss the essential differences between our sand products and their common uses. In terms of colouring, builders sand normally tends to be a light grey colour and can in some instances appear almost white. Sand itself sits between gravel and silt with it’s grains being smaller than those that make up gravel but larger than those that make up silt. DIFFERENT TYPES OF SAND USED FOR BUILDING Many kinds of building materials have multiple uses. 20 tons of Sharp coarse sand (1 tipper) costs between N42,000 to N45,000; 1 tipper of 20 tons of Sharp coarse sand that is not very silty costs between N30,000 to N33, 000 Different process used different types of sands. River sand is Fine-type sand ( I’ll discuss fine sand later in this post). In the construction industry, you’ll hear of two main types of sand. Ravindra Patnayaka B.Arch, M.Tech (Planning) Assistant Professor in Architecture 2. Because sand is used in mortar and concrete for many important parts of the house, including the foundation, concrete for the tie columns and bond beams. There is a method of testing the silt content of sand called (funnily enough) the “silt test”. This sand consists of fine rounded grains and It is well graded. You may have also experienced the situation where you purchase one bag of standard yellow builders sand only to find you run out before the job is finished. To those new to the world of DIY and construction, you may think that sand is just sand but this is certainly not the case, there are quite a few different types of sand, with each specific to certain jobs. Builders Sand – (aka River Sand, Screeding Sand, Plasterer’s Sand, Mason’s Sand or Bricklayer’s Sand) Unlike the sharp sand above, builders sand is much finer due to … Sand is high on that list, if not at the top. Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. To add to the confusion of not only having various different types of sand, each different type of sand can have up to 10 different names depending on the area of the country you’re in and what trade you’re involved in. River sand – This sand is usually gathered from the banks of the river. As the name suggests (e.g. Sand doesn't expand when wet. Clayey composites are described as plastic or cohesive. Types Of Footings Used In Building Construction: Footing is one of the most important parts of a structure which transfers loads of a structure to the underlying soil. 5 Sand & Gravel Options for Construction 1. Keeping with the theme of the name describing where a given type of sand is sourced from, jointing sand or beach sand is collected mostly from beaches and areas around coastlines.  the most common constituent of sand is silica (silicon dioxide, or SiO2), usually in the form of quartz. Unlike the sharp sand above, builders sand is much finer due to the fact that the grains are much smaller. Rock. Sand can be classified based on various criteria. You will also find out what sand actually is and how it's formed and why, sometimes, it can come in a range of different colours. It has a gritty feel to it. Utility Sand: Also known as fill sand, utility sand is rather coarse in texture and is a mix of white, gray, beige, tan, and brown particles. Building stones are the naturally occurring massive, dense rock which can be cut or shaped into blocks or slabs for use in wall, paving, roofing materials or other construction works. Typically, sand and other similar materials such as gravel/grit or silt (commonly found on river beds and river banks) is classified by the size of it’s grains. One other issue is that it also contains chloride and if you have ever witnessed an old piece of metal that’s been exposed to sea air for a period of time, you may have noticed that it’s probably heavily corroded (rusty). The building may develop cracks or damages with use of improper quality of sand. 2. Apologies, but we don't seem to have a video for this project yet, but we will do our best to get one up soon. Would it work to use compacted sand as the leveling “medium,” rather than wood joists, which would have to be tapered because of the sloping concrete? Sand is also used to bond the blocks in the walls. It is used for drainage and terrain preparation when making the foundation of the structure 3. For example, using a very fine sand instead of building sand when making mortar can mean that it doesn’t bond correctly to bricks or blocks and could lead to the structure your building collapsing! In Engineering point of View Sand (Fine aggregate) is classified into following types :- Types of Sand Based on Source Choosing the wrong sand creates problems and is very expensive over time. Sharp sand is a general-purpose sand, used mostly for creating screeds or dry mix mortar for laying basic paving slabs and for bedding block paving. Some create solid surfaces that stand up to foot traffic, while others are ideal for drainage around homes and businesses. Soil can be classified into three primary types based on its texture – sand, silt and clay. Over time, and through the action of the wind, waves and erosion, quartz and feldspar combine (along with other materials such as bone, shell, coral, glass and as many should now be aware, plastic) and forms sand on beaches, river beds and around lakes and other shorelines. It is well-graded and coarse-type sand. A strong foundation ensures that the building is durable against the forces of nature. The depth of the soil at which safe bearing strata exists. Quality of sand is as much of importance as other materials for concrete. Sand gives strength and sustainability to the building. Current Prices of Sand in Nigeria 2020.

It is available in clean condition and can be widely used for all-purpose of construction activities like plastering and concreting. Row by row from left to right: 1. Subscribe to our newsletter and get a free "estimating Cheat Sheet", © 2020. Sandy soil essentially consists of small particles formed by weathering rocks. Sand can be used for construction, sports grounds, homes, schools etc. If you have already read through the above type of sand you should now have guessed that artificial sand (or M sand – manufactured sand) is named as such as it’s artificially created and not naturally sourced. Concreting, Your email address will not be published. It is mixture of silica and 15 to 30% clay with about 8% water. This type of sand is produced from industrial quartz of high quality. Okay. Both of these types of sand are usually bought by the cubic metre, and are best suited to large building projects. (medium sands), 0.06-0.2 mm (fine sands). In terms of how artificial sand is made, generally, it’s produced through crushing up basalt rock or granite rock and due to this is normally greyish in colour. Therefore, it will not cause any structures above it to shift. Knowing when you have high quality sand and what kind it is can help you determine the best application for it. Sharp sand. Building sand is even in grittiness and is used as an essential ingredient for mixing mortar, so having quality building sand is an essential part of the construction process. 2. Due to the coating of iron-oxide, it shows red-orange color. It can be used in … There is a common misconception that concrete blocks are mainly useful for controlling traffic … Design of foundation is based on soil test report of construction site. Row by row from left to right: 1. It’s typically used underneath paving stones (e.g., as a base material for concrete) or even to fill holes and trenches. I however wish to know the maximum sand grain size for the following types of applications: It’s normally used where more strength and less flexibility is required Types of Soil tests for building construction works depend on properties of soil. This soil typically has a mix of organic material, sand and clay. As it’s mainly mined from inland areas away from the coast it does not contain salts that would otherwise allow it to absorb atmospheric moisture and this makes it idea for use in the building trade where moisture and damp issues need to be avoided. Because it has salt in it which attracts the moisture from the atmosphere and causes for dampness, efflorescence, and disintegration of work. This is a naturally occurring material that is found in nearly a quarter of the earths crust. This type of construction sand provides excellent compaction and good mechanical properties due to its uniform grain shapes. And ranging in size from 0.06 mm to 2 mm.Particles which are larger than 0.0078125 mm but smaller than 0.0625 mm are termed silt.. Consider these five sand and gravel options as you move forward with your construction project. Composite soil types: Classified as ‘sandy gravel’ or ‘gravelly sand’. Such as General criteria and Engineering criteria. There are various types of Sands currently that can be used in Construction. From the engineering point of view, the sand can be classified based on various things. Ravindra Patnayaka B.Arch, M.Tech (Planning) Assistant Professor in Architecture 2. Grit sand has a slightly larger grain size than other types of sand, which means it’s also slightly heavier.

Out of them Pit sand, M sand, and River sand are majorly used. Dune sand from the Gobi Desert, Mongolia 3. For construction, sand is commonly used as an ingredient for concrete, with numerous options available depending on what a project needs. The term 'soil' refers to 'The upper layer of the earth's crust, in which plants grow. Coarse Crushed Limestone Gravel Coarse crushed limestone is the largest type of construction gravel. This reduces binding between particles and so can be easily brushed in joints. The selection of a suitable type of footing generally depends on the following factors: 1. The fineness modulus of this sand should be 2.5 to 3.5 and it should not contain more than 4% silt. Based on the size of the particles, the sand can be classified as fine, medium and coarse. Geologists and soil engineers are employed for large projects like damns, highways and buildings. As we have mentioned, if it’s of prime importance that your mortar does match the colour of the existing mortar then you can add certain dye’s and tints that will help you colour-match it. We briefly mentioned above that the silt content of pretty much any sand used in construction should not be greater than 4%. There are various types of Sand currently being used in Construction. It is actually rare to find soil that will not work for cob. The maximum amount of silt in the sand shall not exceed 8%. Plastering Rendering sand is called Leighton Sand or Riverwashed Sand. Particle size: 0.6-2 mm (coarse sands), 0.2-0.6 mm. Please share your opinion in the comments below…, Filed Under: Building Materials Tagged With: Masonry work. Others insist on Leighton Sand which is a bit like heavy brown sugar, midway between building sand and sharp (screeding )sand. Sharp sand has a weak capillarity, when well compacted, the capillarity is so weak, the water won't be able to rise to the super structure easily. SAND  Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. The strength and stability of soil depend on its physical properties. Testing for Sand Silt Content Test. When paving, the sand needs to be salt-free to avoid the paving slabs that lie on top of it being eroded and damaged. Sandstones make up about 20 to 25 percent of all sedimentary rocks. Brick work Obviously, it is used for plastering work. One final point to note with the sand used in construction is that it should be as clean and free from impurities (soil, clay etc) as possible and also, as uniform in terms of grain size as possible depending on the type you are using. Laying paving courses. 3. Plain concrete – It is the simplest kind of concrete that does not require any reinforcement. We generally use this type of sand in concrete. This is due to the fact that if there is a greater silt content then this can seriously effect the structural integrity of the concrete it’s used in. Most commonly used for bricklaying, when mixed with water and cement it creates bricklaying mortar which will allows you to fuse the bricks together. Feldspar is an extremely common group of minerals that makes up nearly three quarters of the earths surface. One important note is that for any concreting or mortar applications, there should be absolutley no more than 4% silt present in the sand. A Civil Engineer . It’s also desirable to use a sand that provides good drainage. Clay textures are often more stable than sand textures because they have better structure. One of the primary ingredients of sand is silica. Based on the grain size of the sand it can be classified as follows –. It is an effective alternative to river sand. Soil types vary by each region and location, but the majority of soil types will work for building cob and earthen structures. After another trip to the builders merchant you then discover the only builders sand they have is a red colour which results in your mortar being two different colours, leaving you in the quandary of whether to just use it as it is or try and colour match it using a mortar tone or other colouring method. … Concrete is a type of course sand usually made of gneiss, trap rock, granite, or limestone. BUILDING MATERIALS - SAND 1. Before we get into exactly what types of sand there are and how each should be used, it would be a good idea to find out what sand actually is and where it comes from. Also a level of permeability is required through joints and a sharp sand due to angular friction will have a good percentage of porosity. Crushed stone sand is commonly used for road construction, and is widely known as a low-cost, high-value commodity. Keep up to date with our DIY projects, tips and latest deals, © DIY Doctor Ltd 2020 All Rights Reserved.
