Polycarboxylate Ether powder for concrete admixture
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 a neutral concentrate grade,It is mainly used as a raw materials to produce differrtet 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 extented 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 blash 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 for the following applications
High performance concrete
Self-compacting concrete
Pumpable or flowable concrete
Concrete containing silica fume,fly ash or blash furnace slag
Specially shaped concrete elements
Architectural concrete
Lighweight 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 dirrectly in concrete or other materials without evaluation.The optimal performance of it in applications should be obtained through trial mixes and or through formalution adjustments by the users.For precast products processed in elevated temperate such as steam curing.
