Performance characteristics of produced PCE basing on HPEG: 

PPEG react with unsaturated Acid such as  Acrylic Acid,Maleic Anhydride. The produced PCE has features of high ratio of effect-cost,high rate of water reducing, good slump retention and excellent durability.

·high ratio of effect-cost. When reaching the same water reducing rate, smaller dosage , higher ratio of effect-cost.

·Lower dosage, higher water reducing rate. When dosage is 1.0% (calculated in quantity of binding materials) basing on 20% solid contents PCE, water reducing rate can reach 30-35%。

·Good slump retention. The slump loss of Concrete in 1 hour is small.

·Excellent durability.Reduce the dosage of water in a lot, improve the durability of concrete.

·Environmental.There are no harmful chemicals such as Formaldehyde, microcrystalline Chloridion and Sulfate Radical in the process of producing PCE.

 

Application field: 

 

The PCE basing on PPEG can be used in retarding concrete,precast concrete,cast -in-place concrete,high performance concrete,flow state concrete,self-compacting concrete and mass concrete. It is widely used in project such as high-speed railway,large bridge,hydroelectric project,nuclear power plant,metro,high way,harbor.

 

Packing specification: 

 Flake in 25KG/PE bag.

 

Store and transport: 

Non-toxic,Non-ignitable. It can be transported as common chemicals. Store it in dry and ventilate place,avoiding sunniness and rain.
