Abstract

When assessing the strength of slag-alkaline binder based on crushing waste, rational proportions of components were revealed. It was found that the samples have a dense and homogeneous structure after hardening. The average compressive strength reaches 41.2 MPa. The results of testing samples from a dry building mixture including slag-alkaline binder with quartz sand are presented. The limits of compressive and bending strength of samples are determined. Diagrams of strength changes depending on the composition of the mixture and changes in the water-binder ratio are given.
