Polycarboxylate Ether for Concrete

Description

It is a new generation superplasticizer for concrete. It contains polycarboxylate ether polymers and is specially formulated for ready-mix concrete where slump retention, high strength and durability are required in hot climates. It is chloride-free, meets SS EN 934, Set retarding/high range water reducing/superplasticizing admixtures, and ASTM C 494 requirements for Type F & G. It is also compatible with all cements meeting the ASTM standards.

It is the ideal admixture for the ready-mix concrete industry. The ability to work with low water /cement ratios and still obtain extended slump retention allows for the manufacture of high quality concrete.

Standards Compliance

PCE/PE complies with the requirements of the following standards: ASTM C 494, Type F; ASTM C 1017 .


Main Use & Advantages

Polycarboxylate Superplasticizer of high slump retention is mainly used in high temperature to formulate pumping concrete. Its main features are as follows:

(1) High water reducing rate: Water reducing rate can be above 30% under optimal dosage (confirmed by lab test).

(2) High slump retention: concrete slump value can be increased to more than 220mm from 70-90mm under the same water cement ratio, and good workability will be kept. There is no obvious slump loss within 30min, or no obvious bleeding. Slump value keeps above 150-180mm within 1h. Pumping ability is excellent.

(3) Long durability: low chloride and alkali content; can decrease concrete long-term shrinkage and shrinkage crack; Concrete shrinkage ratio will be less than 110%. Suitable air content and foaming structure will ensure concrete long durability if our product is used.

(4) Production clean degree is high: Due to formaldehyde, industrial naphthalene, acetone or other flammable and toxic chemicals being not used in production process, it meets cleaning production standard. This new production technology is a fully automated process without heat production.

(5) Safety: non-toxic, no radiation, non-inflammable, no corrosion for steel bar or aggregate, and no formaldehyde, or aromatic residues harmful for human. Our product complies with the current environmental friendly standard of interior and exterior construction.
