Sandcrete is a yellow-white building material made from a binder (typically Portland cement), sand in a ratio of circa 1:8, and water.
Sometimes other ingredients may be added to reduce the amount of expensive Portland cement such as pozzolanas and rice husk ash.
Sandcrete is unsuitable for load-bearing columns, and is mainly used for walls, or for foundations if no suitable alternative is available.
As material for walls, its strength is less than that of fired clay bricks, but sandcrete is considerably cheaper.
[citation needed] Addition of coarse aggregates has been tried, since this is a cheap way to increase compressive strength, but since the cement content of sandcrete is small, so is the amount of water that is added to the sand/cement mix to cure it.
