Which antifreezes can be compounded with polycarboxylate superplasticizers?
Keywords
Polycarboxylate superplasticizer, antifreeze, concrete, antifreeze pumping agent
In winter construction of polycarboxylate superplasticizer, in order to prevent concrete from frostbite, antifreeze can be mixed with polycarboxylate superplasticizer.
Types of antifreeze
Inorganic salts: calcium chloride, sodium chloride, sodium sulfate, sodium thiosulfate, calcium nitrate, calcium nitrite, sodium nitrite, etc.;
Organics: organic triethanolamine, triisopropanolamine, urea, methanol, ethylene glycol, etc.
Through the adjustment of the dosage, the concrete can be constructed under the temperature of -5, -10, and -15 C respectively, so that the antifreeze type pumping agent can be compounded.
