The objective of the present study is to determine the thermophysical properties (thermal conductivity, volumetric heat capacity, thermal diffusivity, and thermal effusivity) of concrete manufactured using two different sizes of coarse aggregates by mixing ratios of 1:1.5:3 for application in building construction. The thermal conductivity and the volumetric heat capacity of these samples were measured experimentally in the dry state at ambient temperature (20°C), and at 28 days of age using a CT-meter. Comparative studies were carried out on the compaction effect of normal concrete with two different types of coarse aggregates G1 and G2. The effect of compaction rate and the bulk density on thermal properties was analyzed. The findings of the study indicate that the size of coarse aggregates along with compaction have an influence on the thermal properties of the tested concretes, which demonstrate a notable improvement with increase in compaction.
