The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.
the general name for a large group of concretes with a density of 1,800–2,500 kg/m3. The binder in heavy concrete is one of the varieties of portland cement; the aggregates are dense ore rocks such as limestones, granites, and basalts. The widespread use of heavy concrete in modern construction results from the high quality of the physicomechanical properties of heavy concrete and the availability of the natural masonry building materials used as coarse and fine aggregates.
