Abstract
For many years, sand has been predominantly used as fine aggregate in civil engineering construction. More recently, the source of quality sand has been fast diminishing resulting in ever increasing cost of construction. Laterite is now seen as a possible replacement for sand in concrete mix. This paper presents the results of the laboratory tests carried out to investigate the ultimate strength behaviour of laterised concrete. Five classes of specimens incorporating 0, 10, 20, 30, and 40% laterite as replacement by weight of sand were prepared. For each specimen class, reinforcement was varied using 2, 3, 4, and 5 numbers of 10 mm high yield bars as tensile reinforcement- with minimum shear provision, at 300 mm centers. When subjected to compressive tests using Avery Denison Universal Testing Machine, the compressive strength of normal concrete beam specimens ranges between 17.48 N/mm2 and 20.39 N/mm2 while that of laterised concrete ranges between 15.29 N/mm2 and 35.69 N/mm2. The analyses showed that laterised concrete beam specimens give satisfactory performance compare to normal concrete beam specimens when the content of laterite in the concrete as partial replacement for sand does not exceed 25%. This result supports the earlier findings that laterised concrete beams can be a satisfactory substitute for normal concrete in building construction.
