Polycarboxylate Ether Powder Form For Concrete Admixtures

Description

Polycarboxylate ether (powder) is high performance 100% polycarboxylate ether polyer,specifically developed a high range water reducing agent for concrete and other mineral materials .

 

It is concentrated from liquid polycarboxylate ether,for convenient transportation purpose,It is mainly used as a raw materials to produce different types of high performance water reducers for targeted industries.

 

Special features

▲Polycarboxylate ether performs water-reducing effect, categorized as ASTM type A admixture with superior benefits from technology and the quality:

▲Very effective, largely reduces required dosage

▲Good stability, producing extended slump life

▲Homogeneous plasticizing property with a unique cohesive characteristic, thus preventing segregation and bleeding

▲Promotes usages of higher dosage or volume of cementitous supplementary materials such as silica fume, fly ash and blast furnace slag.

▲Versatile disperser for various types of cement and minerals including gypsum, ceramic, ion-oxide pigment.

 

Uses

▲Polycarboxylate ether is mainly used as a major ingredient to produce a high performance water reducers or plasticizers etc., concrete admixture for the following applications

▲High performance concrete

▲Self-compacting concrete

▲Pumpable or flowable concrete

▲Concrete containing silica fume, fly ash or blast furnace slag

▲Specially shaped concrete elements

▲Architectural concrete

▲Lightweight concrete

 

It can also be used as-is for above mentioned applications. However due to variations in chemical composites of cements and other materials used and for different application requirements, it is not suggested to use it directly in concrete or other materials without evaluation. The optimal performance of it in applications should be obtained through trial mixes and or through formulation adjustments by the users. For precast products processed in elevated temperate such as steam curing.
