Fosroc Conbextra Gp2 Non Shrink Grouting Powder

Conbextra GP2 page 1 of 4 Free fl ow, high strength, non-shrink, cementitious precision grout Uses Conbextra GP2 is used for precision grouting where it is essential to withstand static and dynamic loads. Typical applications would be the grouting of base plates of turbines, compressors, boiler feed pumps etc., It can also be used for anchoring a wide range of fi xings. These include masts, anchor bolts and fence posts. Advantages  Gaseous expansion system compensates for shrinkage and settlement in the plastic state  No metallic iron content to cause staining  Pre-packed material overcomes onsite batching variations  Develops high early strength without the use of chlorides  High ultimate strength ensure the durability of the hardened grout  Free fl ow ensures high level of contact with load bearing area Description Conbextra GP2 is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a free fl owing, non-shrink grout for gap thicknesses up to 100mm. Conbextra GP2 is a blend of Portland cement, graded fi llers 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 fi llers are designed to assist uniform mixing and produce a consistent grout.
