As a part of a study of the properties of concrete aggregates, thermal expansion determinations were made on 137 specimens of aggregate materials and single crystals by the optical interferometer method thermal expansivities of most aggregate materials are close to or within the range of expansivities of hardened portland cements. Crystal orientation, rock texture! and composition are discussed with regard to their effect on the thermal expansion of aggregate materials and their relation to the durability of concrete.
