Applications include grouting of: „ Baseplates and soleplates of machines „ Structural steel column baseplates „ Voids between precast concrete and infilling blockwork Advantages „ Dual expansion system compensates for shrinkage in both the plastic and hardened states „ High ultimate strength and low permeability ensure the durability of the hardened grout „ Can be dry packed/rammed, trowelled, flowed and pumped „ Hydrogen free gas expansion „ Prepackaged material overcomes potential on-site mixing variations „ No metallic iron content to cause rusting Description 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 C is a blend of Portland cement, specially graded fillers and additives which impart controlled expansion in the plastic and hardened 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, flowable grout. Maximum aggregate size for pumping is 0.3 mm. Standards Compliance AS 1478.2-2005 Appendix E : Test for Early Volume Change. AS 1478.2-2005 Table 4.1.2.2 : Test for 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 C manufactured by Parchem and used in accordance with the manufacturer’s current Technical Data Sheet. Performance specification To the nominated area(s) (specify details and areas of application), grouting must be carried out using a pre-packaged, chloride and hydrogen gas 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. Additionally the grout is to be formulated to compensate for longer term expansion in the hardened state. 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 55MPa at 28 days at a flowable consistency. Fosroc® Conbextra C March 2014
