PHYSICO-MECHANICAL AND HYGROMETRIC PROPERTIES OF POWDER-ACTIVATED HIGH-STRENHGTH GRAVEL CONCRETE AND FIBER-REINFORCED GRAVEL CONCRETE WITH A LOW SPECIFIC CONSUMPTION OF CEMENT PER UNIT OF STRENGTH
The article contains a complex of physical and mechanical and hygrometric properties of powder-activated high-strength gravel concrete and fiber reinforced gravel concrete with a low specific consumption of cement per unit of strength in the range of 2,5-5,0 kg / MPa, with maximum use of their part of the local fine-grained quartz sand 0,14-0,63 mm fraction and industrial waste metals, energy, mining and minerals processing industries. These concretes are designed for the first time in Russia and meet or exceed their foreign counterparts on indicators.
