Specification of Conbextra GP grout non shrink
General purpose non-shrink cementitious grout
Uses
Conbextra GP general purpose grouting is used where it is
essential to eliminate shrinkage when completely filling the
void between a base plate and a substrate. Such an application would be the grouting of a stanchion and machinerybase plates. It can also be used for anchoring a wide range
of fixings. These include masts, anchor bolts, fence posts
and around pipe sleeves.
Advantages
Gaseous expansion system compensates for shrinkage
and settlement in the plastic state.
No metallic iron content to cause staining.
Prepackaged material overcomes potential on-site
batching variations.
Develops high early strength without the use of chlorides.
High ultimate strength and low permeability ensure the
durability of the hardened grout.
Standards compliance
Conbextra GP meets or exceeds the test requirements of
ASTM C 1107.
Description
Conbextra GP 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 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. The low
water demand ensures high early strength. The graded filler
is designed to assist uniform mixing and produce a consistent grout.
