| Popis: | Theoretically proved and experimentally confirmed that on efficiency of action of plasticizing additives in fine-grained mixtures will effectively impact not only the look and flow of the binder, but the type of applied fine filler. The influence of complex additives on the rheological properties of the concrete mix and physico-chemical processes of interaction with the cement matrix of concrete. Found that controlling the adsorption processes of positively charged film on the surface of particles of quartz sand, you can increase the effectiveness of high range plasticizers. |
