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.
