The aggregate grading minimises segregation and bleeding over a wide range of application consistencies. Maximum aggregate size is 5.0 mm. Technical Support Parchem offers a comprehensive range of high quality, high performance construction products. In addition, Parchem offers a worldwide technical support and on-site service to specifiers, end-users and contractors. Specification Clauses Performance specification All grouting (specify details and areas of application) must be carried out with a pre-packaged cement based product, which is non-metallic and chloride-free. It shall be mixed with clean water to the required consistency and not exhibit bleed or segregation. The compressive strength of the grout must be at least 35 MPa at 4 hours (Plastic consistency). The storage, handling and placement of the grout must be in strict accordance with the manufacturer’s instructions. Supplier specification All grouting (specify details and areas of application) must be carried out using Conbextra HES manufactured by Parchem and used in accordance with the manufacturer’s current Technical Data Sheet. 123 Fosroc® Conbextra HES High early strength, rapid setting, flowable, cementitious precision grout Uses Conbextra HES is used for free flow grouting in a wide range of applications where rapid strength gain is a prerequisite. Advantages „ Rapid strength gain facilitates rapid installation and operation of plant within a matter of hours „ High strength gain is achievable even at low temperatures „ Excellent initial flow and flow retention „ Unique system compensates for shrinkage in hardened state „ High ultimate strength and low permeability ensure durability of the hardened grout „ Chloride free „ Suitable for pumping or pouring over a large range of application consistencies and temperatures Description Conbextra HES, rapid set high strength cementitious precision grout, is supplied as a ready to use powder. The addition of a controlled amount of clean water produces a free-flowing grout for gap thicknesses of 15 - 150 mm. In addition the low water requirement ensures high early strength and long term durability. March 2014 Page 1 March 2014
