New Unconventional Additives in Concrete Technology for Expansion its Functionality

Abstract:

Functional enhancement of concrete, giving it heat-resistant properties becomes possible while adding mill ground additions based on silicon carbide materials of the region. The selection of silicon carbide waste and secondary production materials as a filler for the production of concrete with heat-resistant properties was based on the following principles: dispersion, the chemical composition, phase composition that reflect the chemical activity of the material in relation to the concrete binder. The thermal resistance of concrete has increased fivefold. In forming concrete structures with addition of silicon carbide occurs embedding into the structure of hydrates fine powder silicon carbide cyclone dust, with the chemical processes behaviour in the boundary contact zone between binder and filler. The increase of thermal resistance can attribute the resulting concrete composition to the category of heat-resistant concretes, and that significantly expands the functionality of concrete.
