A Review on Recycled Aggregate based Thermal Insulated Concrete
Keywords:Recycled Aggregate Concrete, Performance of Recycled Aggregate Based Thermal Insulation Concrete, Expanded Perlite, Steel Fiber
One of the major challenges of our present society is the protection of environment. Therefore concrete must be such that, it can conserve resources, protect the environment through the utilization of waste materials, economize and lead to proper utilization of energy. In India, the approximate rate of production of construction and demolition wastes is reported to be 14.5 million tonnes annually. The most preferable method of managing these solid wastes is to dump them into the landfills. This creates problems such as pollution in landfill areas and highly increased disposal cost in urban areas. Therefore, recycling and re-using these demolition wastes as recycled aggregates to produce the concrete has been identified as a fruitful way to mitigate the scarcity of natural resources, waste management and environmental issues. Another existing problem is of heat balance, heat always flows from warmer to cooler surfaces. This flow does not stop until the temperature in the two surfaces is balanced. Recycled aggregate alone with thermal insulation material reduce the rate of heat transfer. In this paper a study has been made on the past researches carried out by the different scholars and their results have been studied.
