Polycarboxylate superplasticizer concrete performance indicators Water Reduction /% bleeding rate of not less than 14 ratio /%, not more than 90 gas content /%≤3.0 setting time difference / min initial setting -90- + 120 Final setting Compressive strength ratio /% shrinkage ratio of not less than 1d1403d1307d12528d120 /% and not more than 135 GQ-202 retarding superplasticizer naphthalene superplasticizer is based, and then the composite made of a variety of surface active substances A retarding polycarboxylate superplasticizer liquor, its main feature is incorporated into the product after the concrete has a significant retarding effect, less water is high polycarboxylate liquor production, small flow resistance, slump loss no segregation, no bleeding, and can greatly improve the strength of concrete at different ages, to cement better adaptability, no corrosion of steel for pumping concrete, the flow state, mass concrete and RCC, etc. polylactic acid liquor prices, it is summer concrete project first material.
