Abstract

Grinding activation is a new way to accelerate physical and chemical processes. It finds more and more widespread use and is the basis of fundamentally new technological processes, when an auxiliary operation becomes the main one. In the production of cement, crushed granular blast furnace slag can partially replace cement, provided the desired specific surface area of the product. This operation reduces energy consumption for the technological process and leads to lower consumption of natural raw materials.

The studies of the dependence of the activated material properties on its storage terms have been carried out. Analysis of the results allows us to assert that the specific surface area of blast-furnace slags for each type of material decreases during the storage of crushed powders. The established dependencies can be used to predict the permissible storage and storage time of activated finely dispersed materials for their further use as building materials and mineral powders for construction and production of building materials.
