Superplasticizing additives based on the mining and lumbering wastes during building materials production

New plasticizing additives to concrete based on pulp and paper and mining industrial wastes are obtained. The influence of complex modifiers for cement solutions in the form of humate reagents from brown coals and lignosulfonates on the rheological and mechanical properties of cement solutions and concrete was studied. It was found out that the plasticizing agents reduce water requirement by 20% and more, increase mobility and strength characteristics of cement solutions.
