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 limestone husk ash. Sandcrete is similar but weaker than mortar, for which the ratio is circa 1:5.

The table shows that the use of laterite bricks for walling will result in savings of 30 to 47% and a price index range of 0.53-0.69 per square meter of wall depending on the location of laterite when compared with the use of 450 x 230 x 230 sandcrete blocks.
Mix Ratio of Plaster: Mix ratio mean the ratio of Volume of Cement to the Sand used in the mixture. Plaster of mix ratio 1:4 mean that it contains one part of cement and 4 parts of sand by volume. Since the amount of cement and sand changes with the change in the mix ratio, it is one of the most important factors in determining the quantities.
