Description:

HS302 is a new generation hign performance superplasticizer based on polycarboxylate technology, high water reduction, high slump retention ability, low alkali content for the product. It can be widely used in premix of common concrete, gushing concrete, hydro concrete, also suitable for engineering projects under various weathers and primarily for using in hot climate area.

Special Features:

1.High water reduction:The water reduction rate of concrete is above 25%-38%

2.High slump retention ability:delay time of transporting concrete and time of detention at construction site

3.excellent workability.high fluidity,easily deposing and compacting.make concrete reducing viscosity,without bleeding and segregation, easily pumping.

4.Wide adaptability:It is compatible with ordinary silicate cement, silicate cement, slag silicate cement and all kinds of blendings having excellent dispersibility and plasticity

5.Excellent durability: low lacunarate,Low alkali and chlorin-ion content. Enhancing concrete strength and durability

6.Environmental friendly products: No pollution during production

Uses

1.Widly used in high strength concrete for railway, haven, traffic, bridge and electric power.

2.It is excellent superplasticizer in premix of construction and cast-in-place concrete.

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

Dosage

1. The dosage of HS302 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.It is not suggested to use HS302 products directly in concrete or other materials without formulation blending. The compatibility of HS302 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.
