Fosroc Gp2 Construction Chemical

Product Details:

Free fl ow, high strength, non-shrink, cementitious precision grout Uses Conbextra GP2(N) 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(N) 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(N) 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. Technical support An experienced technical advisory team is available to give technical service on request.

Specifi cation Clauses Performance specifi cation All grouting shown on the drawing must be carried out with a pre packed cement based product which is chloride free. It shall be mixed with clean water to the required consistency. The grout must not bleed or segregate. A positive volumetric expansion shall occur
