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.

Ensuring uniformity of strength of fine-grained concrete based on modified composite cement

“…As shown in [13], the use of surfactants in ultra-small doses to change the structure of water can be an option to overcome these shortcomings. This is the approach used in work [14], which shows an increase in the strength of concrete when the structure of water is changed due to hydrophobic hydration, and in work [15] due to hydrophilic hydration. But even in these works, the homogeneity of concrete strength is not fixed either.…”
