АДСОРБЦІЙНІ ВЛАСТИВОСТІ АЛЮМОСИЛІКАТНИХ МІКРОСФЕР У ЦЕМЕНТНОМУ КОМПОЗИТІ

Abstract

The article presents the results of a study of the feasibility of using aluminosilicate hollow microspheres (ASPM) in cement composites. For this purpose, the adsorption centers on the surface of the ASMM and the electro-surface properties of the components entering the investigated system of dry construction mixtures were determined. The adsorption properties of ASPM in a cement composite are largely determined by the balance of their acid-base centers, which is also related to the sign of the surface charge. The introduction of aluminosilicate microspheres with a size of 5 to 50 μm into the cement composite positively influences the formation of its denser structure at all stages of hydration.
