Sand is produced by crushing rocks. Coarse Stones are produced from the crushing and separation of natural stones, and finer sands, in addition to stones, also contain shells and corals. In civil engineering, aggregates smaller than 75 mm and coarser than 4.75 are called sand. Sands are divided into two categories according to the source and type of grains used in construction.

Sand is one of the cheap materials in the construction industry, paying attention to it can provide you with useful information about the types of Sand and its uses. In fact, it is interesting to know that sands and gravels are divided into different categories in terms of appearance, granulation, and Chemical composition, which we will discuss in this article from Parshin Sazeh's blog; Therefore, according to this introduction, join Parshin Sazeh, the largest database of buildings under construction in the country, to learn more and better.

Sand is the main part of concrete. Considering the resistance of concrete buildings against atmospheric factors and its longer life compared to Metal and Brick buildings; Also, due to the possibility of quick, cheap and easy procurement of materials that are used to build concrete buildings, which is the main part of sand, there is room for more studies on sand.
