Theoretical foundations of the structure formation of cement stone and concrete
Аннотация
Abstract The analysis of resource-saving technologies led to the main conclusion that up to now high-intensity methods for physical modification and hyper-consolidation of concrete mix and concrete have not been developed. Taking into account the physicochemical principles of the structure formation of cement stone and concrete, the production of particularly high-strength concrete (Kb q> 100 MPa) is possible by using methods of modifying the concrete mixture, hyper-consolidation of the molded concrete taking into account the development of the optimal structure of the material, capable of significant stretch perception. The implementation of this idea in industrial production, apparently, is possible using simple technological methods for preparing concrete mixture, forming axisymmetric products, methods of hyper-consolidation of molded concrete and physical modification of concrete mixture, for example, by squeezing excess mixing water and entrained air [1].
