Behavioural Study on Lightweight Concrete

Abundant availability of natural resources has become a dream for present day engineering society due to large scale consumptions. The utilization of fly-ash in concrete as partial replacement of cement is gaining immense important today, mainly on account of the improvement in long-term durability of concrete combined with ecological benefits. The global consumption of natural sand is too high due to its extensive use in concrete, which results in supply scarcity. Therefore, construction industries of developing countries are in stress to identify alternative materials to replace the demand for natural sand. On the other hand, the advantages of utilization of by protects or aggregates obtained as waste materials are pronounced in the aspects of reduction in environmental load. In this context fine aggregate has been replaced by quarry dust. Concrete produced by partial replacing of coconut shell (CS) can be used in plain concrete construction. The use of coconut shell as partial replacement for conventional aggregates should be encouraged as an environmental production & construction cost reduction measures. In this study, the concrete will be made by partially replacing cement with fly-ash, FA with quarry dust, CA with CS. Concrete cylinder and cubes will be casted and test will be conducted for obtaining compression strength, spilt tensile strength, and density result will be compared with conventional concrete.
