Abstract
The paper presents the research results of the influence of grinding fineness and quality of quartz sand on basic physical and technical properties of the new generation powder concrete. It was established that the optimal dispersion of silica filler is in the range of 2800-4000 cm2 /g. It is shown that it is necessary to use pure quartz sand for the production of effective concrete.
