Increasing the water resistance of magnesium binders

Abstract

Abstract In this work, we have experimentally selected concrete compositions based on magnesium binders and optimized with the addition of a butonal. Effects on strength, water absorption and water resistance of concrete, consumption of magnesium binder, sugar mud, and polymer latex Butonal NS 198 additives are investigated. The study was conducted using a two-factor experiment. The algebraic equations of the tensile strength of concrete, water absorption, and softening coefficient were obtained based on magnesium binders, which characterize the dependence on the variables: magnesium binder consumption, sugar mud, and additives. Refined factor values when the optimal ratio of additive components is reached to obtain concrete based on magnesium binder with softening ratio Cs = 0.98, by introducing the butonal into the concrete. The conclusions provide quantitative indicators on the results of these studies.
