FOSROC CONBEXTRA GP 20KG
PRODUCT DESCRIPTION
Conbextra GP, a general purpose shrinkage compensated cementitious grout, is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a flowing non-shrink grout for gap thicknesses from 10 mm up to 100 mm. Conbextra GP is a blend of Portland cement, graded fillers and chemical additives which impart controlled expansion in the plastic state whilst minimising water demand. Low water demand ensures high early strength and graded filler designed to assist uniform mixing and produce a consistent grout. Maximum aggregate size for pumping is <1. 0 mm.
- High ultimate strength and low permeability ensure the durability of the hardened grout
- Gaseous expansion system compensates for shrinkage and settlement in the plastic state
- Can be dry packed, rammed, trowelled, poured and pumped
- Pre-packaged material overcomes potential on-site mixing variations
- Develops high early strength with out the use of chlorides
- No metallic iron content to cause staining
- Complies to AS/NZS 4020:2005 Products in Contact with Potable Water
