NEW CLASSIFICATION OF ACTIVE MINERAL ADDITIVES, INFLUENCING ON DURABILITY OF THE CEMENT STONE

The stone durability of the paste of normal density, consisting the mixed cements with additives on the basis of silicon dioxides (crystalline silica, microsilicon dioxide), corundum, calcium silicates (natural and artificial wollastonite, rankinite), hydrous calcium silicate, (tobermorite, xonotlite), technogenic slags (fuel high-calcic, coal sour, domain) is investigated. The dependence between the stone durability and subtlety of mineral filler and features of a crystal-chemical structure of silicon-oxygen anion of additives is shown. New classification of mineral additives for cement is offered. The influence of a superplasticizer Glenium 115, duration and conditions (heat and moisture exchanger and normal) of curing on stone durability with various mineral fillers including structurally active versions is shown.
