In Botswana the classical, raw material for buildings, e.g. concrete and bricks, is the local river sand. Due to poor annual inflow of river sand and intensive construction in the area of the capital Gaborone, the few traditional resources that exist today are decreasing very rapidly. A major change from the use of river sand to crushed rock is ...
As environmental transportation and other constraints make the availability and use of river sand less attractive, a substitute or replacement product for concrete industry needs to be found.
Manufactured Sand (M-Sand): Produced by crushing rocks, quarry stones, or larger aggregate pieces into sand-sized particles. It has a more predictable grain size and shape, which can significantly enhance the strength and workability of concrete. It is often used as a substitute for river sand in areas where natural sand is not readily available.
