Sažetak
The article found that defects in cement and aggregate grains can not only cause stress concentration and contribute to cracking, but also can stop their propagation. It was determined that, in addition to zones with reduced strength, a zone with an increased viscosity can become a brake on the path of a growing crack, having a modulus of elasticity much less than the modulus of elasticity of the base material. The influence of moulding of reinforced concrete structures on its mechanical characteristics was revealed. It can be stated that mineral additives of various nature, regardless of hydraulic activity degree, optimize the deformative properties of cement stone and concrete with practically constant compressive strength.
