| Popis: | This paper is part of a study investigating the str uctural characteristics of concrete using various c ombinations of lateritic sand and lime stone filler as complete replacement for criver sand fine aggregate. The lime sto ne filler obtained from limestone quarries. The concrete are made using var ying contents of lateritic and lime stone filler as fine aggregate. The quantity of laterite is varied from 0% to 100% against lime stone filler at intervals of 25%. Samples of concre te (eg.cubes and cylinders) are made in three different grades, namely: M15, M2 0 and M25. It was found that 0.55 water/cement rati o produced higher compressive strengths, tensile strength and better workability for M20 mix, proportion. Specifically c ompressive and tensile strength ranged from 21.06 -35.2 N/mm 2 and 10.06 -15.5 N/mm 2 for the mixes considered. These results compare fa vourably with those of conventional concrete. The concrete was fo und to be suitable for use as structural members fo r buildings and related structures, where laterite content did not exceed 5 0%. |
