Abstract

Increase in demand of construction materials in Nigeria has made researchers work extensively on the need to incorporate locally products into production of sand hollow blocks and interlock bricks. This study analyzed the strength and durability of blocks and bricks blended with laterite as a partial replacement of sharp sand at 10, 20 and 30% respectively. A total of seventy-two (72) hollow blocks were produced manually using prefabricated steel moulds of 450mm x 225mm x 150mm and forty-eight (48) interlocking blocks with a mould of 200mm x 100mm x 85mm were subjected to water absorption, density and compressive strength tests. The results showed that 7 and 28 days average compressive strength of nine (9) inches blocks at 10% replacement was 0.76- 1.48?N/mm?^2 and 0.57- 1.30?N/mm?^2 at 30%. However, all blocks produced do not conform to NIS 87:2007 specification- 1.8?N/mm?^2 at age 7days and 2.5?N/mm?^2 at age of 28days. The average compressive strength of the interlocking blocks varied from 1.45N/mm^2- 2.57N/mm^2 and 1.24N/mm^2- 2.33N/mm^2 as the percentage replacement was increased from 0 to 30%, at day 7 and 28 of curing. All laterite interlocking blocks satisfied the minimum 28 days compressive strength of 1.0N/mm^2 recommended by the Nigeria Building and Road Research Institute (NBRRI, 2006). Proper curing and stabilization of laterite were suggested to improve the performance and quality of the hollow and interlocking blocks.
