METHOD OF ACTIVATING BINDING PROPERTIES OF MINERAL INDUSTRIAL PRODUCTS

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of activating binding properties of industrial mineral products in form of ash or slag containing calcium oxide, silica and alumina. In the method for thermal activation of binding properties of mineral industrial products in form of ash or slag containing calcium oxide, silica and alumina, involving heating the product, holding at given temperature followed by cooling and fine grinding, the ash or slag is heated to temperature 1200-1350 C for 3-5 minutes, held at said temperature for 5-10 minutes and then cooled to 800-1000C for 1-2 minutes. ^ EFFECT: high hydraulic activity - strength of the slag or ash. ^ 3 tbl
