Abstract :

Sand is a well–known building material and has occupied a very important place in construction work but Sand is more expensive because it is more difficult to collect sand from rivers. With the fast depleting state of natural resources like river sand and aggregates, it is time to look for alternative cheap materials (marginal materials) for making concrete, particularly when strength is not a primary parameter. One of the potential marginal materials for use in concrete is laterite. This paper presents the results of the laboratory tests carried out to investigate the suitability of using laterite as partial replacement of sand. At the rate of 0%, 15%, 30% by weight for design mix of M25 controlled concrete. A total of 18 specimens of size 150mm x 150mm x 150mm are prepared to determine the cube compressive strength after 7, 21 and 28 days of curing. The laterite sand used is available in Humnabad region, Bidar District of Karnataka state as a replacement of Gulbarga area best available river bedded sand in concrete. Data results revealed that the laterite fines used could satisfactorily replace the sand up to 30%.
