Monolithic Concretes on the Basis of Expanding Agents and Chemical Modifiers

The information on basic advantages of the monolithic construction technology is presented. Issues of improving qualitative and technological characteristics of ready-mixed concretes including durability and crack resistance are considered. Compositions of concrete composites with water tightness W16 and frost-resistance F300 have been developed with the use of expanding agents and complex of chemical additives. The results of tests of compositions of concrete mixes for slump retention vs. time and changing the air entrainment when agitating in the truck-mounted mixer are presented. Ii is shown that expanding agents in cement composites create the dense structure, reduce the permeability including diffusion, which prevents the corrosion of concrete and steel reinforcement.
