High Range Pumping WaterReducing Admixture, MNC-P2 Type

MNC-P2 type high rangepumping water reducing admixture is a new tan powder additive that consists ofprincipal naphthalene-based superplasticizer,some retarding component and air-entraining component. It is applicable tocommercial concrete, big flowing concrete, mass concrete and pumping concretemixed on-site.

Our high range pumping water reducing admixture is an ideal material to producehigh-quality pumping concrete with less than 80 carbon atoms. It featuresstable chemical properties, good safety performance, non-toxic, odorless,noncombustible, non-crystallization in winter, above 22% of water reducingrate, early strengthening function, good durability, small concrete shrinkageand good adaptability to various cement especially mixed with superfine mineraladmixture. Besides, it controls premature hydrationeffectively and has distinct retarding effect on initial set by 10 hours oraccording to customer’s requirement for appropriate adjustment. With small lossin 2 hours and certain air content, our product can efficiently improveconcrete flexural strength, elastic modulus of concrete, waterproof andimpermeability.
