FOSROC CONBEXTRA C 20KG
PRODUCT DESCRIPTION
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 shrinkage compensated grout for gap thicknesses from 10 mm up to 100 mm. Conbextra C is a blend of Portland cement, specially graded fillers and additives which impart controlled expansion in the plastic and hardened state whilst minimising water demand. The low water demand ensures high early strength. The graded filler is designed to assist uniform mixing and produce a consistent, flowable grout. Maximum aggregate size for pumping is 0. 3 mm.
- Dual expansion system compensates for shrinkage in both the plastic and hardened states
- High ultimate strength and low permeability ensure the durability of the hardened grout
- Can be dry packed/rammed, trowelled, flowed and pumped
- Hydrogen free gas expansion
- Prepackaged material overcomes potential on-site mixing variations
- No metallic iron content to cause rusting
