polycarboxylate water reducer

Principle of function Molecular main chain of polycarboxylate high performance water reducer is firmly adsorbed on surface of cement granule where can efficiently counteract hydration reaction and increase its plasticity. Branched chain surround cement granule having sterically hindered and electrostatic exclusion function which is different from conventional imparts excellent dispersing ability and effect of water reducing which make integrative characteristics of concrete improve greatly. Methods of use 1.The dosage of SPE-100 is suggested as follows(wt.% of cement):0.25%-0.8%. 2. It can be mixed in metric water or added in concrete mixer. The recommended stirring time is 150s at least. Concrete mixing test should be made before using in order to insure concrete quality. 3.It can be compounded together retarder, defoamer, air-entertraing reagent,lignin sulfonic natrium and so on. 4.SPE-100 product is sold as raw materials. It is not suggested to use SPE-100 products directly in concrete or other materials without formulation blending. The compatibility of SPE-100 products to particular cement, aggregate and the other raw materials in the application is not guaranteed. It should be obtained through trial mixes and formulation technologies by the users.
