Effect of Elevated Temperature on Diverse Properties of Concrete Containing Waste Materials

DIVERSE PROPERTIES OF CONCRETE CONTAINING WASTE MATERIALS

Abstract

Among the growing industries around the globe, concrete industry has been contributed significant role to the national economy. The most widely used construction material and the second-most consumed material in the world after water is concrete, which has been employed as insulation in applications involving high temperatures. This extensive review has been highlighted the best possible extracts from the literature on the assessment of thermal effects on various properties of concrete containing various waste products, in particular. Few enhanced performance after being subjected to high temperatures have been reported when industrial by-products are replacing conventional ingredients. Various mechanical properties of concrete after exposure to elevated temperatures have been recapitulated and reviewed. Effect of elevated temperature on many significant physicochemical, mechanical, microstructural changes in concrete made with various materials such as waste slags, recycled coarse and fine aggregates, silica fume, fly ash, crumb rubber, etc. have been vividly summarized and compared. Better performances for concrete incorporating recycled aggregates under exposure to elevated temperature have been reported from the results. Finally, the authors have made an attempt to summarize the short-comings in the specific field of research and discussed on available future scopes on utilization of various industrial by-products in sustainable concrete production under elevated temperature.
