A method for evaluation of microdamages in rock and aggregate from the index of effective porosity and water absorption, based on the modern concepts of the rock destruction theory, is proposed. A reduction in stone durability was found to be closely related to the formation of microfractures on the rock surface. It has been shown that, together with the mineral composition, size and shape of a crushed grain, one of the essential factors that affect the strength of aggregate and are responsible for its durability is the microfracturing of rock. It has been proved that technological conversion of rocks in production of construction materials (aggregate) substantially changes the physico-mechanical characteristics of material in comparison with their initial indices.
