TF-8202 is a new excogitate environmental polycarboxylate type slump retaining agent. It is benefit for low slump concrete and concrete of losing slump rapid. Greatly enhance plasticity of concrete. It is canary viscous liquid, no toxic, hazardous, and corrosive.

Production Characteristic

1).Good slump retaining ability: It can inhibit the reaction rate of hydration.

2).Slow release: It is low initial water reduction and high later, it has excellent dispersion for cement.

3).High strength gained rate: Greatly increasing early and after strength, reducing energy loss.

4).Special adaptability: It can be widely used in premix of common concrete, gushing concrete, high strength and durability concrete.

Technical Specification

TF-8202 Polycarboxylate Type Slump Retaining Agent

Methods of Use

1).The recommend mix proportions is superplasticizer: TF-8202 = 8:2-7:3 (mass ratio).

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-entertraning reagent, lignin sulfonic natrium and so on.

4).TF-8202 product is a product as raw materials. It is not suggested to use TF-8202 products directly in concrete or other materials without formulation blending. The compatiblity of TF-8202 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.

Scope of Application

1).It is especially suitable high strength concrete for railway, haven, traffic, bridge and electric power and so on.

2).It is suitable for the preparation of high strength, high durability, self-compacting, steel fiber and self-leveling concrete.
