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 Description Conbextra GP, a 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 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 0.7 mm. Standards compliance AS 1478.2-2005 Appendix E Early Volume Change AS1478.2-2005 Table 4.1.2.2 Consistency Technical support Parchem offers a comprehensive range of high quality, high performance construction products. In addition, Parchem offers technical support and on-site advice to specifiers, end-users and contractors. Specification clauses Supplier specification All grouting where shown on the drawing must be carried out using Conbextra GP manufactured by Parchem and used in accordance with the manufacturer’s data sheet. Performance specification To the nominated area(s) (specify details and areas of application), grouting must be carried out using a prepackaged, chloride free, dry powder blend of cements, graded fillers and chemical additives. It is to be mixed with clean water to the required consistency. The plastic grout must not bleed or segregate. The storage, handling and placement of the grout must be in strict accordance with the manufacturer’s instructions. A positive volumetric expansion of 1-3% shall occur while the grout is plastic by means of a gaseous system. It shall exhibit Flow Characteristics when tested to AS 1478.2.2005 of 10 - 30 seconds using the flow cone procedure. The compressive strength of the grout must exceed 45MPa at 7 days and 65MPa at 28 days when used at a flowable consistency. Fosroc® Conbextra GP March 2014
