ELITE-INDUS
High Range Concrete Polycarboxylate Superplasticizer 40% 50% ELT-WR
Description Of Polycarboxylate Superplasticizer ELT-WR
Polycarboxylate Superplasticizer ELT-WR is a polycarboxylate based high range water-reducing admixture which enables concrete to be produced with very low water to cement ratios.
Polycarboxylate Superplasticizer ELT-WR does not contain added chlorides and will not promote corrosion in steel.
ELT-WR is compatible with air-entraining agents, microsilica, accelerators and many other admixtures.
however, each material should be added to the concrete separately.
ELT-WR complies with the requirements of the following standards: ASTM C 494, Type A & F. BS EN 934-2.
ELT-WR It can improve the flowability of concrete while significantly reduce the mixing water of concrete.
It has high water-reducing rate (40%) to meet the performance requirements of self-compacting concrete, high-performance concrete and precast.
And it also has the function on early strength.
Characteristic Of Polycarboxylate Superplasticizer ELT-WR
◆ High water reduction: The water reduction rate of concrete is above 40%.
◆ Easying to control production: Controling water reduction ratio,plasticity and air entraining by adjusting molecular weight of main chain,length and density of side chain, type of side chain group.
◆ Good dispersion: High fluidity of concrete results in deposing and compacting easily for self-compacting concrete.
◆ High strength gained rate: Greatly increasing early and after strength,reducing energy loss. Reduction of cracking, shrinkage and creep.
◆ Wide adaptability: It is compatible with ordinary silicate cement, silicate cement, slag silicate cement and all kinds of blendings having excellent dispersibility and plasticity.
◆ Good strength and durability: low lacuna rate, low alkali and chlorin-ion content.Enhancing concrete strength and durability.
◆ Environmental friendly products: No pollution during production.
◆ Low-consume, Low-cost: It can be produced in little cycle and little-consume.
So it having low-cost. Especially it can be used in commercial concrete.

Methods of use Of Polycarboxylate Superplasticizer ELT-WR
◆ The dosage of ELT-WR is suggested as follows (wt.% of cement): 0.25%-0.8%.
◆ 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.
◆ It can be compounded together retarder,defoamer, air-entertraning reagent,lignin sulfonic natrium and so on.
◆ product is a product as raw materials.
It is not suggested to use ELT-WR products directly in concrete or other materials without formulation blending.
The compatiblity of ELT-WR 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.
Application Of Polycarboxylate Superplasticizer ELT-WR
