Abstract
Increment in production and deployment of energy-efficient buildings caused growing demand for environmental conservation. The most desirable by-product produced from power plant is fly ash cenosphere. It has white color, hollow structure and spherical shape. Addition of phase change materials (PCM) in concrete mixture contributed in improving thermal regulation in buildings. It was found that density, splitting tensile strength and compressive strength are decreasing when the percentage of cenosphere increased. Concrete mortar with 20% of cenosphere shown the lowest compressive strength, tensile strength as well as density. The thermal conductivity of concrete mortar also shown reduction when high percentage of cenosphere was introduced which is 0.5�W/m�K. It can be concluded that the incorporation of certain percentages of cenosphere and PCM can improve both mechanical and thermal properties. � 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
