Introduction Name:Calcium Chloride Formula:CaCl2 Assay:74%,77%,94% Calcium Chloride CaCl2 As Building Antifreeze,it is an inorganic salt with calcium and chlorine.Calcium chloride exists in anhydrous and dihydrate forms.Calcium chloride can accelerate the hardening of concrete and increase the cold resistance of building mortar, which is an excellent building antifreeze agent. Application Calcium chloride can accelerate the hardening of concrete and increase the cold resistance of building mortar, which is an excellent building antifreeze agent. Commonly used calcium chloride antifreeze is used for roads or housing construction (construction industry) in the process of antifreeze, to protect roads or buildings. When dissolved in water, calcium chloride fills in the Spaces between the water molecules, preventing them from freezing at sub-zero temperatures because the molecules aren't arranged in the same way they normally would. In the process of road maintenance or building construction, the use of calcium chloride antifreeze can achieve normal construction in low temperature environment, protect the road and building wall roof and foundation from damage due to low temperature. The mechanism of calcium chloride antifreeze has the following effects on concrete: change the concentration of the liquid phase in concrete, reduce the freezing point of the liquid phase, so that the cement continues to hydration under negative temperature; Calcium chloride antifreeze to reduce the water consumption of concrete mixing, reduce the amount of water that may freeze in concrete at the same time, the most likely pore size in concrete is reduced, further reduce the freezing temperature of the liquid phase, change the shape of ice crystals, the introduction of a certain amount of small closed bubbles to slow the frost heave stress; Improve the early strength of concrete, enhance the ability of freezing resistance of concrete.
