Product Information

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. Apart from sand, silica is found in a great many other materials, both naturally occurring and man-made materials. Some of these include quartz (one of its most common occurrences), clay, glass, silica gels and also in some food stuffs and medicines. Without colouring, can anyone recommend how to get a strong pointing mix that is a sandy colour? The original pointing was strong cement so we are planning on a like for like. 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.

The reason for this is down to where the sand has come from. 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. 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. Aside from the size and shape of grain and where the sand originated from another very important fact that should be considered is how clean the sand actually is. By this we mean establishing its silt content. Biogenic/ Bio-organic Sand: Sand who’s makeup is largely from coral, shells and the skeletons of marine life

Next, it’s a waiting game! The jug should be left for at least 3 hours for everything to settle. Once settled, all you need to do then is measure the layer of silt that has settled on top of the sand.

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!): Beach sand is also known as washed sand which relates to the way in which it’s processed in that it is washed through to remove any unwanted dust, clay, silt, sediment etc. after which it is then left to thoroughly drain. We briefly mentioned above that the silt content of pretty much any sand used in construction should not be greater than 4%. Olivine Sand: Not suitable for use in construction applications due to the fact that it’s unstable, but is used for creating casts and moulds for steel In terms of the grains that make up beach/jointing sand they do tend to be very fine and through the action of the tides swooshing everything around do also tend to be very smooth and rounded.I have tried adding in a little Snowcrete and it does soften the colour a bit to allow some sandy tones but it's still not proper sand coloured. 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. Why Does Sand Come in Different Colours? 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 dyes and tints that will help you colour-match 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. Aside from the main or common types of sand above, there are other less common type available that are used mostly in specialist applications:
