Physical and Mechanical Properties of Fine-Grained Concrete Produced using Water Purified by Natural Adsorbents

The main part of drinking water consumption falls on powerful industrial facilities, however, the requirements for water used in technological processes are much lower than for drinking water. This work has shown that water contaminated with sulfates, after purification with natural adsorbents, comes up to the requirements of the standard. Determination of the initial and residual concentration of the pollutant in the solution was carried out through the control of electrical parameters, the so-called conductivity method. The purified solutions were used for the production of fine-grained concrete and the strength of the finished products was determined on the 28th day of hardening. The suitability of such solutions for use in the concrete industry was established not only from the point of view of suitability according to standards but also from the point of view of ensuring the required strength.
