Polycarboxylate Superplasticizer Preservative(KH-807)

Release time:2017-07-14 Author:admin
Product introduction
In the process of synthetizing and copolymerization of polycarboxylate superplasticizer preservative, add directly polyhydric alcohol modifier and hydroxyl to increase density of lateral chain to improve dispersing. The polycarboxylate superplasticizer preservative can be widely used in the constructions of road, bridge, dam, tunnel and high-rise buildings, etc. The J90 preservative has a strong dispersion effect on cement, can greatly improve the concrete slump and fluidity of cement mixture. At the same time, reduce water consumption by a large margin and significantly improve the workability of concrete, thus improving concrete strength at different stages.
Product advantages
The polycarboxylate superplasticizer preservative J90 is of good compatibility with various kinds of cement, good performance of maintaining concrete slump, extending the construction time of concrete.Low amount of admixture, high water reducing rate and small shrinkage. 
Significantly improve the concrete strength of early and late stages.This product is low chlorine ion content and low alkali content, which is helpful to the durability of concrete. There is no pollution or formaldehyde generated during the 
the manufacturing process of polycarboxylate superplasticizer preservative J90 which is a kind of green environmental protection product and meets the international standards of ISO14000 ISO14000 environment management system.
The polycarboxylate superplasticizer preservative J90 is suitable for the precast concrete, cast-in-place concrete,reinforced concrete and prestressed concrete of high speed railway and passenger transport line, industrial and civil buildings, roads, bridges, ports, airports and other projects.Particularly applicable to nuclear power engineering which projects requires long hours of concrete preparing and construction time and good maintaining of concrete slumps.
Under normal circumstances, when converted solid content is 20%,the polycarboxylate superplasticizer preservative J90 is 0.5 ~ 1.5% of the weight of cementing material, the recommendeded amount of admixture is 1.0%.
