The effect of granulate porosity on the evolution of the thermal conductivity of an resin concrete exposed to high temperatures.

As the aggregates occupy about three-quarters of the volume of concrete, it’s not surprising that their properties can, not only, to limit its resistance, but also to affect the durability and structural performance of concrete. In this context, the study's main objective to study the influence of the aggregate porosity on the evolution of the thermal conductivity of a resin concrete exposed to high temperatures. the experimental results show that the porosity of the aggregates has a significant influence on the evolution of the thermal conductivity of the concretes tested.
