One important note is that for any concreting or mortar applications, there should be absolutley no more than 4% silt present in the sand.

Sand 15kg - Orange Coloured Sand 15kg - Orange

In terms of colouring, builders sand normally tends to be a light grey colour and can in some instances appear almost white.

Specially washed, graded, dried and coloured with a rounded grain which is safer for kid's play areas. If it helps, I am looking for the sandy colour that this chap was able to get in his "this is how it turned out" picture (but funnily enough he wanted more grey!

Feldspar is an extremely common group of minerals that makes up nearly three quarters of the Earth’s surface. 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. Unlike the sharp sand above, builders sand is much finer due to the fact that the grains are much smaller. 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. But with a 4:1 mix and standard Blue Circle cement, both come out largely grey (the golden sand comes out a lighter grey).

After giving half a bag of sand to a neighbour, I bought exactly the same red/orange Tarmac builders sand again and the mix is drying light grey. More often than not, sharp sand or pit sand has a orangy red colouring as it is often found in areas with concentrations of iron-oxide. As mentioned, silica or fine rock particles forms the bulk of a body of sand and quartz tends to be the most common material that effectively forms the silica.

Different Types of Sand and What They Should be Used for Different Types of Sand and What They Should be Used for

Sand itself sits between gravel and silt with its grains being smaller than those that make up gravel but larger than those that make up silt. The sand conforms to BS71 - Part 1, 2 and 3 for toy safety standards and BSEN 11 77 for impact absorbing play surfacing. Now that you know why some sand is a different colour to other sand you may also be thinking, why would it suddenly change colour even though I’m getting it form the same place?Sand produced in one area of the country may have a slightly higher iron-oxide content, giving it a reddy orange appearance, where as sand from another area of the country may feature more coral or shell content giving it a whiter appearance. In terms of the grains, unlike the coarse sharp and angular grains that make up sharp sand, the grains found in builders sand are much more rounded and smoothed off. The orange sky is similar to the dramatic scenes seen in California in 2020 when a plume of wildfire smoke mostly blocked out the sun in the city of San Francisco, leading to a day when the sun appeared not to rise.

It’s used to make concrete and mortar, bricks and blocks, glass, casting moulds and many other things. 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. Hoping that one of them will come out to have a warmer shade of grey; but they don't look like they will be anything like the orginal attached image. Using the right type of sand for the particular job you are doing is hugely important as using the wrong grade can be disastrous.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. It’s primarily used in making concrete as due to the shape of the grains, it binds extremely well to form a tough and solid surface, but due to the size and shape of particles, not that smooth. 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.
