Sandcrete blocks are masonry units manufactured from a mixture of cement, sand and water. They are predominantly used as walling materials in construction of residential houses and other infrastructures. The composition of a sandcrete block is usually (1:6) mix of cement and sand moistened with water and allowed to dry naturally [1].
Blocks are those building unit used in the construction of walls and partitions. Sandcrete block is a composite material made up of cement, sand, water, molded into different sizes [1]. Sandcrete blocks can be made either in solid and hollow rectangular types.
In the whole, quarry dust block is cheaper to make than the sandcrete block. And the most significant factor for the difference in their cost implication is the great difference in the cost of their basic material (i.e. sand and quarry dust). The cost of quarry dust is less than 50% of the cost of river sharp sand …

Sandcrete blocks constitute a unique class amongst man-made structural component for building in civil engineering work. For example in buildings, walls are constructed (using blocks), as either load bearing or non-land bearing to provide shelter,
Sandcrete blocks comprise of natural sand, water and binder. Cement, as a binder, is the most expensive input in the production of sandcrete blocks (Hornbostel, 1991). This has necessitated producers of sandcrete blocks to produce blocks with low OPC (Ordinary portland cement) content that will be affordable to people and with much gain.
Sandcrete blocks are the most common type of blocks used in forming walls units and over 90% of houses in Nigeria today are being constructed using sandcrete blocks (Baiden and Tuuli, 2004). The importance of the sandcrete blocks as part of the local building materials cannot be over emphasized in the building and construction industry.

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 similar but weaker than mortar, for which the ratio is circa 1:5. Soil cement and landcrete are similar materials but ...
