Conbextra GP
General purpose, high flow, Class A shrinkage compensated grout – (gaps 10 mm to 100 mm thickness).
Description
Conbextra GP is a general-purpose shrinkage-compensated
cementitious grout, 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 10mm up to 100mm.
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. The low
water demand ensures high early strength. The graded filler
is designed to assist uniform mixing and produce a consistent
grout.
Maximum aggregrate size for pumping is 0.7mm.
Uses
Conbextra GP is used for general-purpose grouting where
It is essential to eliminate shrinkage when completely filling
voids or grouting between a base plate and substrate, e.g.
The grouting of a stanchion base plate. It can also be used
for anchoring a wide range of fixings, such as masts and
anchor bolts.
Advantages
- 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 without the use of
chlorides - No metallic iron content to cause staining
