ABSTRACT: This article presents the results of studying peculiarities of structure formation in concretes with regard to technogenesis. Dependencies of water and cement requirements on particle size composition of technogeneous sands used as fillers in concretes are shown. Properties of concrete mixes and concretes, depending on main characteristics of fine filler, have been studied and justified. Practical conclusions have been formulated, based on analysis of fine-grain sands for possible wide use of technogeneous sands in production of fine-grain sands.
