​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
â–²Polycarboxylate ether performs water-reducing effect, categorized as ASTM type A admixture with superior benefits from technology and the quality:
â–²Very effective, largely reduces required dosage
â–²Good stability, producing extended slump life
â–²Homogeneous plasticizing property with a unique cohesive characteristic, thus preventing segregation and bleeding
â–²Promotes usages of higher dosage or volume of cementitous supplementary materials such as silica fume, fly ash and blast furnace slag.
â–²Versatile disperser for various types of cement and minerals including gypsum, ceramic, ion-oxide pigment.
Uses
â–²Polycarboxylate ether is mainly used as a major ingredient to produce a high performance water reducers or plasticizers etc., concrete admixture for the following applications
â–²High performance concrete
â–²Self-compacting concrete
â–²Pumpable or flowable concrete
â–²Concrete containing silica fume, fly ash or blast furnace slag
â–²Specially shaped concrete elements
â–²Architectural concrete
â–²Lightweight 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.
