Product Description

Polycarboxylate Superplasticizer (polycarboxylate ether/based superplasticizer) is a high performance concrete superplasticizer, use as concrete dispersant in cement. CAS:9009-54-5. It has a strong role for the cement particle dispersio, fully enhancing and improving various properties of concrete. High performance Polycarboxylate water-reducing agent is a new generation superplasticizer. Our product has good compatibility with a variety of cement. High water reduction and shrinkage characteristics, make possible to improve the performance of concrete slump, extend the construction period. Besides, it also can greatly improve the flow of concrete, increasing early and late strength, ensuring project quality. Widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects. The green product, non-flammable, non-explosive, can be safely transported by train and car.

Application

Applicable to the configuration of high-strength concrete, pumping concrete, high performance concrete, self-compacting concrete vibration-free. Widely used in commercial concrete, mass concrete, high strength concrete, high-rise buildings, roads, bridges, tunnels, underground engineering, water power station. Deatails as below:

1. Recommended dosage (by binding materials’ weight) is 0.25%-0.80%. The optimum dosage is according to the reality project conditions and actual materials.

2. polycarboxylate ether liquid can’t be used with naphthalene water reducer. Compatibility test should be done in advance when used with other additives.

3. Precise measurement avoids repeat dosage, seep dosage and errors.

4. polycarboxylate ether liquid can be widely used in all brands & kinds of concrete admixtures or cements .

Advantages

1, Good compatibility with various kinds of cement, concrete slump to maintain good performance, the construction time of concrete.

2, Low dosage, high water reducing rate, shrinkage.

3, Greatly improve the early and late strength of concrete.

4, Low chlorine ion content, low alkali content, is conducive to the durability of concrete.

5, Non polluting, non formaldehyde, in compliance with international standards ISO14000 environmental protection management, is a kind of green environmental protection products.

6, Once poly carboxylic acid salt water reducing agent used, cement can be replaced by more slag or fly ash, thereby reducing the cost.
