Introduction:
The model RO - JS is a new type of modified super plasticizers researched developed on our own based on polycarboxylic high performance plasticizers. The product has the advantage of high water-reducing rate, low air content and better dispersiveness over average super plasticizer. What's more, the product in made by advanced process and its every comprehensive indicator is good therefore it has higher cost - effective advantage. This product complies with super plasticizer indices by GB8076- 2008.
