Thermal Properties of Concrete by Replacement Sand with Porcelain Waste

Abstract

Thermal mass gives significant benefits in building design, because property of a material enables it to absorb and store heat energy. The aim of this work is to determine the thermal properties of concrete by replacement of sand with porcelain waste. Sand is replaced with porcelain waste at different percentages of 10 %, 20 %, 30 %, 40 % and 50 %. The samples were prepared from cylinder concrete and cut it by the concrete cutter to produce the required specimens with a diameter of 4 cm and 0.5 cm thickness, hot plate method was basically employed throughout the experiment. Furthermore, the thermal conductivity, specific heat capacity and thermal diffusivity of the samples were measured. The addition of porcelain waste in the concrete were increased the thermal conductivity, specific heat capacity and thermal diffusivity and the results were obtained2.31 (W/m.K), 974 J/kg⋅K and 0.9800 mm2/s respectively at 50 % replacement and 60 days. The usage of porcelain waste in concrete has great potential in the construction industry in the future.
