ABSTRACT
Calculation and experimental bases of cement hydration degree influence on the cement stone strength and its change over time at extremely low values of water-cement ratio and various specific surface area of cement are given. The monograph presents algorithms for obtaining and analysing experimental-statistical models of strength and other properties of high-strength rapid-hardening concrete and ways for design on their basis optimal concrete mixtures compositions. For various fiber-reinforced concrete compositions, shrinkage deformations, frost resistance, residual flexural strength were studied and the optimal conditions were determined to achieve their required values. An important advantage of fiber-reinforced concrete is the increased dynamic characteristics. The experimental-statistical models obtained in the research enabled to propose the methodology outlined in the monograph for design of optimal high-strength fiber-reinforced concrete compositions, providing a set of their normalised properties at the lowest possible cost.
