Fosroc Epoxy Grout Conbextra EP75, Joint Width: Of 10 To 75 mm

Product Details

Conbextra EP75High strength, epoxy resin grout Uses Provides a free flowing grout, for use where physical properties and chemical resistance of the hardened grout are of utmost importance. It is suitable for a wide range of heavy duty applications including : ?? Underplate grouting to substantial structural elements. ?? Base plate grouting in dynamic load situations such as turbines and other reciprocating machinery. ?? Heavy industrial applications in steelworks, refineries chemical plants and electroplating works. ?? Structural infill where very high strength is required. ?? Rail track applications, to support heavy cranes, or on transporter rails. Advantages ?? Excellent durability - high compressive, flexural and tensile strengths ensure a long working life. ?? Cost effective - high early strength gain promotes minimum downtime and early commissioning of plant. ?? User friendly - simple, full pack mixing to ensure that the performance characteristics are achieved. ?? Versatile - suitable for a wide range of loading situations including repetitive dynamic loads. ?? Excellent in service performance - non-shrink capability ensures full surface to surface contact. Description Conbextra EP75 is a solvent free epoxy resin grout designed for grouting of gap widths of 10 to 75 mm. It is supplied as a three component system consisting of base, hardener and specially graded aggregate. The components are supplied in the correct mix proportions designed for whole pack mixing on site. Specification Where shown on the contract documents, the epoxy grout shall be Conbextra EP75 supplied by Fosroc. It shall provide good general chemical resistance, 7 day compressive strength of at least 100 N/mm2 and a compressive creep of 2.85N/mm² in accordance with ASTM C1181Base plate If delay is likely before placing steel base plates, it is recommended that the underside and edge are coated with Nitoprime 25* to prevent rust formation and ensure bonding with the Conbextra EP75 grout. All metal surfaces should be cleaned to a bright finish in accordance with Swedish Standard SA 2½or equal. Nitoprime 25 can be applied directly onto newly cleaned steel surfaces even if they are damp. Mixing The entire contents of the hardener can should be poured into the base container and mixed until homogeneous. Place the mixed base and hardener into a suitable forced action mixer making sure that the entire volume is poured in. Add the aggregate and mix for 2-3 minutes or until uniform colour is achieved. Once mixed, the material must be used within the specified pot life (see under Properties). After this time, unused material will have stiffened and should be discarded. Note: Immediately prior to placement, all surfaces must be dry. Placing Ensure that the grout can be placed within its pot life. Continuous grout flow is essential. Sufficient grout must be available prior to starting and the time taken to pour a batch must be regulated to the time taken to prepare the next one. Pouring should be from one side of the void to eliminate air entrapment. The hydrostatic head must be maintained at all times so that a continuous grout front is achieved. Cleaning All tools and equipment should be cleaned immediately after use with Nitoflor Sol*.
