Concrete Admixture Polycarboxylate Superplasticizer PCE Liquid Water Reducing Type

ELT-WR30 is a polycarboxylate based high range water-reducing admixture which enables concrete to be produced with very low water to cement ratios. ELT-WR30 does not contain added chlorides and will not promote corrosion in steel. ELT-WR30 is compatible with air-entraining agents, microsilica, accelerators and many other admixtures; however, each material should be added to the concrete separately.ELT-WR30 complies with the requirements of the following standards: ASTM C 494, Type A & F. BS EN 934-2.

Product Description Of ELT-WR30:

ELT-WR30 is a polycarboxylate based high range water-reducing admixture which enables concrete to be produced with very low water to cement ratios. ELT-WR30 does not contain added chlorides and will not promote corrosion in steel. ELT-WR30 is compatible with air-entraining agents, microsilica, accelerators and many other admixtures; however, each material should be added to the concrete separately.ELT-WR30 complies with the requirements of the following standards: ASTM C 494, Type A & F. BS EN 934-2.

ELT-WR30 is high-performance aqueous dispersion agent, which is special designed for self-compacting concrete, high-performance concrete and precast components. ELT-WR30 is key ingredient in admixture of concrete.

It can improve the flowability of concrete while significantly reduce the mixing water of concrete. It has high water-reducing rate(35%) to meet the performance requirements of self-compacting concrete, high-performance concrete and precast. And it also has the function on early strength.

Typical Analysis Of ELT-WR30:

Natural Characteristics: Polycarboxylic Acid Aqueous Solution

Appearance (20℃) : Light Yellow To Brown Liquid

Solid Content (%)  40 ± 1%  50 ± 1%

PH Value (20℃) : 5~7  

Proportion (20℃): 1.08 ± 0.02

Chloride Content (%): < 0.01  

Alkali Content (%): < 1.5


Features of ELT-WR30:

High water-reducing rate

Achieve high efficiency at low dosage

Low air-entraining effect

Broad adaptability with many kinds of cement

Advantage of ELT-WR30:

Improve productivity of the concrete

Reduce the comprehensive cost of the concrete

Improve the workability of the concrete

Promote the growth of the concrete strength

As polycarboxylates high performance water-reducing admixture,ELT-WR30 can be used to design high-performance admixture products.

 

Application of ELT-WR30:

ELT-WR30 is widely used in the production of self-compacting concrete,high performance concrete and various precast. It can significantly reduce the water consumption and improve the workability and early strength of the concrete.When ELT-WR30 is compounded with other varieties of admixture, please pay attention on the compatibility, and it should be tested before used.

 

Using Method Of ELT-WR30:

The recommended dosage is 0.4%~0.6% (based on weight of cementing material).The most suitable dosage should be finalized according to the materials and characters of project and tests.

Can be mixing with water, or can be added into the concrete batching plant separately.

Can be mixed with high plastic retention type polycarboxylate superplasticizr and all kinds of retarders.


Examples of ELT-WR30:

Product in an ready-mixed concrete mixing station, the proportion and performance of concrete are showed in following tables:

It can be seen from the above results that the slump degree and expansion degree of concrete formulated with ELT-WR30 can meet the design requirements, and the concrete shows low viscosity, flow speed and good workability, it is fully able to meet the construction requirements of self-compacting concrete.

 

Storage of ELT-WR30:

Sealed storage if unused,storage temperature is 0~40℃

Storage period to maintain optimum performance is 24 months.

 

Safety Precautions Of ELT-WR30:

Polycarboxylate superplasticizer ELT-WR30, if direct and prolonged contact with eyes and skin may cause irritation. Wash the affected area of body with plenty of tap water immediately. If irritations persist for long time, please contact with doctor.
