Increasing the water resistance of magnesium binders

摘要

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.
