Results of a Study on Obtaining of the Humic Containing Plasticizers and Their Influence on the Physic-Mechanical Properties for the Cement and Concrete Mixtures

摘要

In the modernization of the technology on concrete the important significance has physical chemistry and colloid chemical ideas about mechanism and to the kinetics of the processes of structure formation in the dispersal systems and questions on the influence of different chemical additives, regulated performance properties of concrete. The chemical additives of the organic and inorganic origin, which are introduced into the composition of concrete they contribute to a change in the kinetics of forming of micro-, the macrostructure concrete mixtures due to the adsorptive modification of hydrated phases, formed in the initial setting time and hardening of the binding materials, decrease water-requirements, increase mobility and fluidity of concrete mixture", increase frost resistance and strength indices of concrete.
