Polycarboxylate Ether Powder Form For Concrete Admixtures
Decription
Polycarboxylate ether (powder) is high performance **0% 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
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 extented 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 blash 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 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 blash furnace slag
â–²Specially shaped concrete elements
â–²Architectural concrete
â–²Lighweight 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.

Special notes
Do not use it with additives containing naphthalene sulfonate.Unreliable rheologic hehaviours may be experienced
Do not use it for temperature treated concrete or other materials
Packing
Availble in *5kgs/bag.
 
Storage
It should be stored at temperature ***0℃(*****4F).When it freezes,full strengthe can be restored after complete thawing and thorough afitation.Keep container closed when it is not in use.Do not store the product directly under sunlight.
Shelf life
