Slump retaining polycarboxy acid superplasticiser

KH-207 is a workability retaining and slump retention admixture for use in concrete applications. This product meets the requirements of ASTM C494, Type A & S.

KH-207 contains the latest time released polycarboxylate polymer technology, allowing controlled slump extension depending on project needs and actual concreting conditions.

·Exnt Slump retention: KH-207 is designed to be meet the needs of different concrete slump protection through the optimization of the synthetic formula and process.Due to utilization of a new engineered time released polymer allowing controlled and consistent slump extension with minimum initial slump increase,KH-207 allows to transport freshly mixed concrete for larger distances without need of retempering at the job site.

·Water Reduction:Working as a slump retention admixture,KH-207 also has a initial water reduction rate,and the strength growth and structural development of hardened concrete are also significantly improved.

·Workability retaining:KH-207 shows a slow release in the initial half hour, but still can meet the construction demand,and in one hour to two hours, the release will reach the peak and maintain good workability for long slump retention time as required.

·Wide adaptability: KH-207 can be used as a stand-alone additive or in combination with any Huaxuan concrete admixture.Concrete admixture added by KH-207 gains a strong adaptability to various raw materials of concrete, and efficiently improving the dosage sensitivity caused by the mud in sand and gravel.
