Abstract
The Nigerian Building and Road Research Institute (NBRRI) has been involved in the development of an interlocking Compressed Stabilized Earth Block (CSEB), produced from laterite stabilized with the cement of 5% weight using a minimum compaction effort of 3N/mm2 to achieve sustainability within Nigeria’s construction industry. This investigation concerned itself with determining the effect of Fire Resistance on the compressive and abrasive strengths of the NBRRI interlocking CSEB for a wide range of applications towards achieving sustainability. Several laboratory and workshop activities were carried out in the formulation, molding, curing and testing of the Blocks using standard procedures. At 5% stabilization of the laterite classified as silty SAND, the blocks after being exposed to controlled fire at varying temperatures from 200 0C to 850 0C was discovered to have the highest compressive and lowest abrasive strength of 2.37 N/mm2 and 0.29 cm2 /g respectively at 850 0C, and lowest compressive and highest abrasive strength of 1.21 N/mm2 and 3.28 cm2 /g respectively at 200 0C. This suggests that the blocks have less capacity to resist wearing off after exposure to severe fire. Hence, Blocks produced with identical formulation may necessarily require plastering after fire incidents.
