The thermal performance of manufactured concrete roof tile composite using clay and rice straw fibres on a concrete mixture

Abstract

This paper presents a review of research on the development regarding concrete roof tile composite using clay and rice straw on concrete mixture to produce sustainable building materials in reducing indoor temperature during hot and dry weather. Architects today are less stressed about the impact and significance of roofing material to reduce indoor air temperature in the building design. Concrete roof tile is an exceptionally strong product and can endure wind and storm that would tear up other roofing types. Because of its excellent strength, concrete roof tile can withstand lifetime of your home. It is less expensive than many of the roofing tiles that it competes with a wonderful combination and its longevity. Nevertheless, concrete roof tile is non-heat insulation and also rather heavy. The combination of concrete with clay can make the concrete roof tile as a bad conductor, become heat insulation material and reduce indoor temperature level. Rice straw is the natural fiber consists of great thermal to improve indoor air quality and alleviates the issue of the weak mechanical strength of combination with concrete and clay. Besides, it can reduce the density of concrete because it has a lower density than other fibers.
