【 摘 要 】

Designed the composition of the fiber-reinforced concrete on composite binder with high gas-, water- and steam impermeability. With 1.6% of reinforcing steel anchoring a fiber can be obtained in terms of the maximum physical and mechanical properties (Rcompr= 100.9 MPa). It was found that the combined effect of mechanical and chemical activation (the presence of limestone particles) increases the pozzolanic activity of acidic environment. It has a catalytic effect on the reaction activity of the surface of ash and sand during machining in vario-planetary mill. Furthermore, the introduction of limestone increases the alkalinity of the concrete, which leads to the formation of greater hydration products of cement per unit of time. Theoretical and experimental results can be recommended for enhanced implementation of the construction in various regions of the World, taking into account the availability of raw materials.
