Abstract

The ability of a structure to retain its structural integrity in adverse conditions of weather and fire out break depends on its durability and fire resistance. This research work investigated these indispensable properties in Laterite Rock Concrete to assess its usability structural concrete. Durability was investigated in terms of water absorption, density, shrinkage and fire resistance. Fire resistance test was carried out using direct fire test. Two mix proportions: 1:2:4 and 1:1½:3 were tested at optimum water/cement ratio of 0.6 and 0.55 for 1:2:4 and 1:1½:3 mixes respectively. From the results, it is concluded that the concrete is durable, environmentally compatible and possesses high fire resistance properties, having satisfied the relevant codes requirements. The 1:2:4 and 1:1½:3 conform to the specifications for grades 15 and 20 correspondingly. Recommendations include specifications for designing structural elements using the Laterite Rock Concrete.
