Performance characteristics of produced PCE basing on TPEG:  

The produced PCE has features of small dosage,high rate of water reducing, good slump retention,stable concrete volume and non-corroding to rebar.

 

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 26-30%。

Good slump retention. The slump retention of Concrete in 1 hour can be above 80%.

High strength.Comparing with the normal concrete, the strength of testing concrete is higher.ratio of compressive strength (%): 1day≥160,3day≥150,28day≥140 .

Excellent durability.decrease the water-binder ratio of concrete, enhance the dense of concrete,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 TPEG 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.
