AB  - Experimental analysis of thermo-physical properties of concrete is necessary in order to determine a concrete composition suitable for thermal energy storage. This study carries out a laboratory experimentation in order to obtain the absolute thermal conductivity, resistivity and diffusivity of different composition of concretes with their strength test and it was discovered that concrete mix of ratio 1:2:0 (cement:sand:gravel) has the highest compressive strength of 74.5 N mm<SUP>-2</SUP>, lowest thermal conductivity of 0.51 W/m&deg;C thermal storage capacity of 2.74 J m<SUP>-3</SUP>K while the mix of ratio 1:1.2:1.1 has the highest thermal storage capacity of 3.22 J m<SUP>-3 </SUP>K and that of ratio 1:1.9:1.7 has the highest thermal conductivity of 1.7 W/m&deg;C.
