Sand plays a very important part in the construction of a school. It's part of the foundation, it's used in making the bricks and it's part of the mixture in the concrete.
For that reason it is very important that we use the right kind of sand. There are several different kinds of sand, sand which is mixed in with the earth, sea sand, desert sand and fresh water river sand. The only type of sand which is properly suitable for construction purposes is the freshwater river sand. This is not always readily available but nonetheless even if it means trucking it in from a long distance away,it is the only type of sand we ever use .
In the first photo grainy , raw earth sand , and in the second photo smooth and fine freshwater river sand.
