Operation and destruction of concrete at high and low temperatures

Concrete and reinforced concrete structures during operation are exposed to various aggressive influences, including those associated with high and low temperatures. The most common aggressive action causing destruction is the effect of low temperature, which leads to freezing of moisture in the concrete body. Another common impact is the effect of high temperature on unprotected concrete due to the occurrence and development of fire. At high temperature effects on concrete and reinforced concrete structures there is a decrease in their strength and stiffness, including irreversible, due to the violation and change in the structure of the hardened Portland cement. The possibility of further operation of such damaged structures, their recovery is determined by the results of the surveys. Scientific developments in the field of concrete operation under extreme temperature conditions are actively conducted, methods of protection are developed and methods of calculations are improved.
