Low Water Reducing Admixture Polycarboxylate PCE Liquid Elt-SR18 18% High Slump Retention

Product Description

 Low Water Reduce 18% High Slump Retention Polycarboxylate Superplasticizer PCE Liquid Elt-SR18

1, Product Description

ELT-SR18 is aqueous dispersion agent with strong slump retention performance, which is special designed for concrete that require high

standard of slump retention. ELT-SR18 is also key ingredient in admixture of concrete.

It has very strong slump retention performance, it shows high water reducing rate, it also significantly extends plasticity time of concrete,

at the same time it adapt with most cement well.

2. Production Characteristic

• High water-reducing rate
• Achieve high efficiency at low dosage
• Low air-entraining effect
• Broad adaptability with many kinds of cement
• 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

3, Specification:

4, Methods of use

1. The dosage of ELT-WR 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-entertraning reagent, lignin sulfonic natrium and so on.

4. 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.

5, Scope of application

1, for the preparation of various levels of pumping concrete,long-distance transport of commercial concrete.
2, suitable for high-strength concrete, fluidized concrete,self-compacting, mass concrete, high performance concrete,concrete structure of water.
3, for a variety of civil works, high-rise reinforced concrete frame structure, Especially for highway, railway, bridge engineering, tunnel engineering,

hydraulic dams, nuclear power engineering, ports, docks,and other underground facilities that require high durability of concrete large concrete

structure, but also for large prestressed concrete beams, plates production , steam curing concrete and so on.

6, Packing:

It has been successfully applied in large volume backplane of a engineering. The concrete always maintain well workability during the

transportation and pumping up to four hours, it lays good foundation for the smooth construction. The proportion and performance of

concrete are showed in following tables:

Form 1——Concrete mix proportion

Form 2——Performance

It can be seen from the above results:ELT-SR18 is strong in slump retention and good for workability of concrete, makes the construction easy,

it is polycarboxylates high performance slump retention admixture.
