Optimization of grain composition and moisture content of the raw mix in the technology of hyper-pressed concrete bricks

Abstract

The prerequisites for the optimal design of granulometric compositions of building mixes for the production of pressed concrete on a cement bond, based on the regularities of the formation of polydisperse structures, are described. An experimental method for determining the optimal granulometry of raw mixtures with the most dense packing of grains, providing the best compaction parameters of mixtures when hyperpressing, is presented. The influence of the moisture content of the raw mixture on the packaging of its particles and bulk density, as well as the strength of the finished material, taking into account the action of capillary coupling in dispersed systems, is shown.
