Methods for the prevention of spontaneous destruction of concrete
Spontaneous destruction of concrete usually combined. There is gas, atmospheric and chemical corrosion. The result is a deterioration in properties up to the complete destruction of the functionality of the structure. First, the components of concrete are blurred and washed out, then elements are formed in which there are no astringent properties, in the final there is an accumulation of low -quality crystallizing salts that destroy the structure of concrete.
In order to protect concrete and increase the durability of his service, you must use the primary and secondary protection. Primary protection is carried out by adding a variety of modifying additives, which do not allow the material to be divided – stabilizers, create an increase effect – plasticizers, water -adhesing, regulating hardening, as well as changing the density and cellularity of concrete.
