dc.description.abstractThis paper examines the variation of work ability and characteristic strength of laterized concrete (concrete containing laterite fine aggregate instead of sand) with different water/cement ratios and mix proportions. Four mixes of cement : lateritic soil: crushed granite were considered, namely I: I : 2, I: 11: 3, I: 2 : 4 and I: 3 : 6. Two methods-slump and compacting factor tests were used for the workability while the conventional cube test was used for the compressive strength. Cubes (100 mm) were made, water-cured at 21 +2°C and tested at 7 and 28 days. The results showed that the water requirement for a mix increases with increase in laterite/cement ratio. Associated with slump test are: zero, true, partial collapse and collapse slumps. The strength decreases with increase in laterite/cement and water/cement ratios. It was further found that the workability decreases with increase in laterite/cement ratio. The results indicated that the well established variations of workability and compressive strength of normal concrete with water/cement ratios are valid for laterized concrete.en_US
