Abstract: Sustainability and reduction of CO2 emissions are important for construction, and the use of fly ash materials to replace cement to reduce CO2 emissions is receiving renewed interest. This study investigates the thermal properties of normal strength concrete with different percentages of fly ash materials in cement in early concrete age. In this study, six concrete mixes are made, one as a control mix and five mixed with different fly ash replacements. The percentages of fly ash cement replacement are 5%, 10%, 20%, 30%, and 40%. The temperature profile, concrete compressive strength, and concrete tensile strength are studied for early concrete age. The preliminary test results show that as the percentage of fly ash replacement increased, the thermal heat decreased and the concrete compressive and tensile strength increased.
