Abstract:

Production of blocks used for wall construction have different techniques adopted which could be in form of hollow or solid blocks produced in varying shapes laid with mortar. The improved form of mortar-fewer blocks which can be used as structural component for masonry building construction is called interlocking block. This brings about economical production, reduced cost of labor and appreciation of available local materials for construction thereby eliminating the use of mortar in lying of blocks. In this project lateritic blocks were casted due to the unavailability of interlocking mould. These blocks were stabilized by using varying percentage of cement by weight of laterite soil (i.e. 5 %, 10 % and 15 % cement), varying percentage of GGBFS replacing cement (10 % and 25 %) and rubber latex (5 %, 10 % and 15 % rubber replacing water) and its strength is determined and compared. Compressive strength of commercial lateritic interlocking block was determined. By interpreting various data and results regarding commercial lateritic block, stabilized laterite blocks were casted. This project presents the results of the experimental investigation carried out brick stabilized with cement, GGBFS and rubber latex as it affects the compressive strength of laterite blocks. Hand compaction and machine compaction methods were used. Curing was done by immersing the bricks in water. Data results shows that more compressive strength is achieved with lateritic block stabilized with cement and rubber latex for both hand compaction and machine compaction. The minimum requirement of strength for bricks used as load bearing wall is 3.5 N/mm2. Stabilization of lateritic bricks with cement and rubber latex meets the required standards. The results also showed that a cement content of 15 % is necessary for meeting the requirements of load bearing wall.
