TEMPERATURE EFFECT ON STRUCTURE PARAMETERS AND PROPERTIES OF CEMENT SYSTEMS WITH ORGANO-MINERAL MODIFIERS
Keyword(s):
The article views changes in strength, phase composition of new growths and diff erential porosity of ultra-high-strength cement systems with organo-mineral modifi er under three temperature modes: under normal conditions at the temperature of 20 °C, after steam treatment at 80 °C and after heat treatment at 200°C. It is shown that the heat treatment at 200 °C signifi cantly modifi es the phase composition and pore structure of cement systems and allows to increase the strength of fi ne grain concrete by 42% and bring it to 188 MPa, what makes possible to refer it to ultra-high-strength concretes, defi ned as «Reactive Powder Concrete».
