EXPERIMENTAL STUDY ON PARTIAL REPLACEMENT OF FINE AGGREGATE WITH RICE HUSK IN CONCRETE

Burning of Rice husk has becoming a major environmental issue. This leads to the raise of greenhouse gases in the environment which ultimately leads to depletion of ozone layer and raise in global temperature. In this project we are investigating the effect of Rice Husk on concrete. Use of this waste material in place of natural resources like Fine Aggregates is a best alternative. We had decided to replace the Fine aggregates with rice husk as 0%, 10%, 15%, 20% and 25% by using M20 grade of concrete. We compared the specimens after partially replacing them with fine aggregates. The specimens had been tested for Slump cone, Compaction factor test and Compressive strength at 7, 14, 28 days interval which is kept at room temperature. The main purpose of this experiment is to study the properties of concrete with partially replaced rice husk. By doing so we can conserve the natural resources. Fine aggregates prices are soaring. Replacing Fine aggregates with waste product Rice Husk will not only reduce the cost but also saves the earth by reducing the greenhouse gas emission.
