Laterite stone have traditionally used after directly extraction from the naturally occurring laterite sources, after which they are cut into brick-like shapes for use as walling units. Recently, there has been advancement in using laterite in the form of interlocking bricks used to construct walls without the use of cement mortar. Laterite stone is ground and filtered using a sieve, which is then mixed with 5% cement mixture and a chemical setting agent. This mixture is then machine compressed to form high density interlocking bricks. They are manufactured in two widths of 6 inches and 8 inches; and are also available in varying lengths. Each interlocking brick has grooves and locks on its sides which can be fitted with each other to form a block wall that does not need cement mortar for bonding. They have lower embodied energy due to use of natural locally available materials- stone and wood. The only energy spent is in transportation of materials. The high recycle ability factor especially in case of interlocking blocks which dont use connecting mortar is a bonus.
