Abstract

In recent years there has been a depletion of natural resources, consumption of fossil fuels and a dire need for conserving energy. Thermal storage concrete is a new type of concrete that is likely to store and conserve energy and thereby serving towards a greener environment. Concrete is considered a suitable media to store energy due to its ability to maintain its performance upon exposure to elevated temperatures, its relative-ease in preparation and widespread use worldwide.

In this work aims at achieving better understanding of factors influencing thermal storage concrete. Twelve concrete mixtures were prepared using conventional, rubber and recycled aggregates and were made with various w/c ratios with and without silica fume. Mixtures were tested for fresh properties as well as compressive and flexural strength upon exposure to high temperatures for six hours.  Using models and valid equations, concrete heat capacity, conductivity and other relevant heat storage properties were assessed.  This study provides useful information regarding the foremost concrete mixtures that are likely to serve for thermal energy storage purposes.  The role of various mix design factors in this regard are discussed and categorized
