Abstract
The use of low-modulus mineral additives in pressed products for road construction
Incoming article date: 04.03.2021The possibilities of using volcanic tuff as an additive in pressed cement-mineral composites intended for road construction are studied. The influence of low-modulus mineral additives of trepel, granulated blast furnace slag and volcanic tuff on the physical and mechanical properties of hardened composites is studied. The rational compositions of the molding masses of the optimal structure of cement-mineral composites providing the improvement of physical and mechanical properties are determined.
