Effective composite binders

Abstract

Nowadays, many countries of the world are witnessing the tendency of refocusing the building materials industry upon the types of concrete, whose distinguishing characteristic is the reduced consumption of portland cement. The studies aimed to develop effective composite binders and expand the raw materials base for their manufacturing are also becoming rather relevant. From this perspective, the products of volcanic activity are of special interest due to their high concentration all over the world. The largest cluster of this raw material in the Russian Federation is located in the Kamchatka peninsula. For this reason, the research on finding optimal technological parameters of manufacturing fine ground cement with the application of igneous-sedimentary rock of the Kamchatka peninsula was carried out. The obtained results enabled revealing the dependencies (compression resistance and time for manufacturing binders on the quantity and initial surface area of the igneous-sedimentary rocks), allowing one to optimize the parameters of manufacturing fine ground cement together with providing maximum rigidity at minimum power costs required for its grinding
