Optimization of Water Activation Technology for the Production of Fine-Grained Concrete

Abstract:

One of the main active components of modern concrete is water. Water has a variable structure, the type of which depends on the water treatment technology. The use of water in the production of concrete, which has a changed structure as a result of the action of certain substances, 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 study is to determine the influence of the type of plasticizers used for water activation on the speed of structure formation and the strength of fine-grained concrete.
