Influence of mineral powders on the properties of binding systems
Introduction. Development of formulations of multicomponent binder compositions with the use of mineral additives of different nature is an urgent task. Multicomponent binders, “Portland cement – mineral additive”, “Portland cement – mineral additive – plasticizer” allow to expand the range of binde...
