FOSROC CONBEXTRA UW 20KG
PRODUCT DESCRIPTION
Conbextra UW is supplied as a ready to use powder. The addition of a controlled amount of clean water produces a free flowing grout. The grout exhibits exceptional resistance to 'washing-out' of the cement phase when placed in stationary or moving water. Conbextra UW is a blend of cement, graded fine aggregate and chemical additives which impart controlled expansion, water reduction and non wash-out characteristics. The aggregate grading minimises segregation and bleeding whilst assisting the flow characteristics. Maximum aggregate size for pumping is 0. 3 mm.
- No risk of significant ‘wash-out’ of cement phase when placed underwater
- Displaces water effectively
- Gaseous expansion system compensates for shrinkage and settlement in the plastic state
- High early and ultimate strength
- Chloride free
- Pre-packaged needing only on-site addition of water
