By modeling the areas of elastic and microplastic deformations of high-strength self-compacting concrete was established of increased crack resistance by the criterion of crack opening due to restrained shrinkage of concrete with the addition of metakaolin. This is explained to the reaction of metakaolin and CaSO4‧2H2O of cement with the formation of additional ettringite and low-calcium hydrosilicates with a decrease of shrinkage deformations and fragility of fracture. The positive effect on the shrinkage of concrete of replacing part of the cement by mineral additives is also explained by the reduction of autogenous shrinkage of concrete due to decreasing cement content, and reduction of drying shrinkage of concrete due to adsorption binding of capillary moisture by fillers. The introduction of mineral additives to replace of cement leads to a decrease of fragility of high-strength self-compacting concretes (increasing of area microplastic deformations) due to increased content of fine crystalline calcium hydrosilicates and gel-like neoformation.
