To the question of the influence of the intensity of active centers on the surface of mineral fillers on the properties of fine-grained concrete

Abstract

The paper presents the results of experimental research on the evaluation of the possibility of using the indicators of surface activity of dispersed minerals as a criterion for determining the most effective way of their application in cement concrete. The obtained results allow to recommend to use such fillers as: quartz sand, barchan sand, wastes of electro smelting production for filling of cement concretes by the method "filling of cement in concrete": gliege, basalt, wastes of copper smelting production, fly ash of thermal power stations, zeolite-containing rocks for filling of cement concretes by the method "filling of cement in concrete".
