Abstract

The present work contains an approach to the evaluation of binary cements prepared with a 20% substitution of coal-mining waste and their behaviour under a maximum of 300 freeze/thaw cycles. Mineralogical studies are conducted, as well as tests on mass variations, compressive strength, microporosity, the dynamic modulus of elasticity, and SEM morphologies. It is important to highlight that the partial replacement of cement by 20% of activated coal waste, does not affect the durability against freeze/thaw cycles, since they show a fairly similar tendency to the reference mortar under extreme temperature changes.
