A Review on Compressive and Tensile Strength of Concrete Containing Rice Husk Ash and Coir Fiber
Journal Title: Scholars Journal of Engineering and Technology - Year 2014, Vol 2, Issue 5
Abstract
Cement manufacturing industry is one of the carbon dioxide emitting sources besides deforestation and burning of fossil fuels. The global warming is caused by the emission of green house gases, such as CO2, to the atmosphere. Among the greenhouse gases, CO2 contributes about 65% of global warming. The global cement industry contributes about 7% of greenhouse gas emission to the earth’s atmosphere. In order to address environmental effects associated with cement manufacturing, there is a need to develop alternative binders to make concrete. Consequently extensive research is on going into the use of cement replacements, using many waste materials and industrial by products. To reduce the impact on the environment due to industrial and agricultural waste products such as Rice Husk Ash (RHA) and coconut fibers (COIR) which are the waste products of paddy and agricultural industry. Use of these materials in concrete not only improves the strength of concrete but also leads to the proper disposal of these materials, resulting in reducing the impact of these materials on environment. It is found that the rice husk ash is obtained by burning of rice husk in a controlled way, which is highly reactive pozzolonic material and the coir having excellent mechanical and physical properties to be utilized in effective way in development of composite materials. This paper describes about the results obtained from various research done on the partial replacement of cement with RHA and COIR in concrete. Keywords: Rice husk ash, coconut fiber, Global Warming, Green house gas, Carbon Dioxide
