Increasing the Speed of Formation of the Structure of Fine-Grained Concrete and its Strength

Abstract:

It was determined that the active component of modern concrete is water. Water has a variable structure, the type of which depends on the temperature at which the water was processed. The use of water in the production of concrete, which has a certain changed structure, allows influencing the rheological properties of concrete mixtures and modifying the structure of cement stone in such a way as to give concrete properties that ensure high operational reliability of structures. However, this method of increasing the strength of concrete has certain disadvantages that prevent its wide application. The purpose of the research is to determine the effect of a mixture of water of different structure on the strength of fine-grained concrete and the speed of its formation.
