APPLICATION OF CARBOXYMETHYL CELLULOSE (CMC) IN THE PRODUCTION OF DRY MIXTURES

The use of special additives (modifiers) in the creation of formulations for modified dry mixtures is due to the need to obtain certain technical and technological characteristics of these materials and, first of all, to the need to retain water in the mixed solution after its application. Water is absorbed into the base and evaporates from the surface of the solution, which leads to a reduction in the residence time of the cement in the gel phase, a decrease in the degree of hydration and, as a consequence, to a decrease in strength
