EFFECT OF ACTIVATED FILLER AND IRONSILICATE ALKALINE COLLOIDAL SOLUTIONS ON DEFORMATION AND ADHESION PROPERTIES OF THE CEMENT STONE
The results of research of the effect of activated filler and ironsilicate alkaline colloidal solution on cement stone shrinkage and its deformation under loading, as well as on the durability of its adhesion with concrete surface and metal are considered in the article. Introduction activated ironcontaining filler into Porltland cement of 20% and ironsilicate alkaline colloidal solution in the amount of 0,5% of cement weight leads to decrease in cement deformability under loading. At that same time the speed of cement deformative properties formation is higher in comparison with cement without additives. As the result it was proved that cement paste containing activated filler and ironsilicate alkaline colloidal solution has adhesion durability with metal and concrete not less than adhesion strength with cement stone without additives.
