As we all know, the service life of ordinary concrete flooring is generally not very long. Because thermal expansion and contraction, weathering, chalking, abrasion resistance and other conditions directly affect the service life of the floor, concrete sealingcuring agentDesigned to improve the hardness of the flooring, making it more wear-resistant. It also has good frost, wind and seepage resistance, thus greatly improving the overall life of the flooring.

　　1, improve the frost resistance of concrete

　　Improve the frost resistance of concrete is to improve the ability of concrete to withstand repeated freezing and thawing in a water-saturated state, saturated concrete in the freezing and thawing, in which the freezable water turns into ice, with a volume increase of 9%. When the ice is confined in the pores, it will produce a huge expansion pressure, so that the internal structure of the concrete is loose, after the ice melts, the structure can not be recovered again, and the concrete will be destroyed.Concrete sealing curing agent is the use of collodion material to block the pores in the structure. Thus improving the frost resistance of concrete, avoiding the destruction of concrete structure.

　　2, weathering resistance, for the exposed concrete part, by the weathering effect more direct

　　From the point of view of improving the permeability and frost resistance of concrete, concrete sealingcuring agentIt is a new type of low-carbon environmentally friendly material. It is non-toxic, odorless, non-flammable, non-volatile and harmless to the environment. Prepared with advanced technology and catalyst, it can penetrate into the surface of concrete about 5-8 millimeters through the capillaries of concrete, react with the active calcium metal ions and free alkali in concrete to generate a gel with cross-linked structure. Thus, a dust-free, dense whole is obtained, which greatly improves the surface hardness and strength of concrete, and increases the abrasion resistance and weather resistance. At the same time, concrete sealer can make concrete dense, effectively inhibit water, oil and other corrosive substances to invade the pore. Fundamentally slow down or prevent concrete corrosion, improve the performance of concrete, greatly extend the service life of concrete.

　　3、Improve the permeability of concrete

　　Concrete is a non-homogeneous porous composite material, pore is one of the important components of the microstructure of concrete, by the gel pore and capillary pore two types of composition, gel pore and C-S-H structure, the size of a few nanometers, and the existence of pores between the different hydration products between hundreds of nanometers to a few millimeters.
