Abstract
n recent years, the attention of researchers is shifting towards the optimization of
building materials by using local contents, indigenous materials, and local
industrial by-products that are abundant in certain localities. This study investigates
the effect of sand on the properties of cement–laterite interlocking blocks. Cement laterite interlocking blocks were prepared with lateritic soil which was replaced with
conventional fine aggregate (sand) from 5 to 25% by weight. Cement-laterite
interlocking blocks without sand (0%) served as control. The blocks produced were
tested to determine their density, compressive strength, and tensile strength. The
average density of cement-laterite interlocking blocks increased as the percentage
of sand content in the blocks decreases. The highest compressive strength (9.1
MPa) at 28-day curing of the cement-laterite interlocking blocks was obtained at
5% sand replacement, which is about 13% increase in strength over the control
blocks. It was further revealed in the stress-strain relationship result that the 5%
sand replacement of laterite achieved the highest stress while the 15% replacement
achieved the highest strain of the cement-laterite interlocking blocks. The highest
tensile strength (0.707 MPa) at 28-day curing of the cement-laterite interlocking
blocks was also obtained at 5% sand replacement, which is about 9% increase
strength over the control blocks. The study concludes that the sand replacement
laterite in cement-laterite interlocking blocks have the potential of supporting the
sustainable housing concept, and therefore recommends to manufacturers 5%
sand replacement of laterite in producing cement–laterite interlocking blocks
