It is ideal for grouting in small gaps between a base plate and substrate which needs filling and the structural load be uniformly distributed. Typical applications are reciprocating machinery, testing equipment, heavy crane and transporter rails, high speed turbines, centrifuges and drop forges. Also for use in conditions where chemical spillage may be encountered. Typical situations could be met in steelworks, refineries, electroplating works and chemical plants. Due to the low viscocity of Conbextra EP10 it can be used to fill hairline cracks in concrete slabs from 0.25mm and upwards on horizontal surfaces using a gravity fed method. Advantages „ High compressive, tensile and flexural strengths „ Resistant to repetitive dynamic loads „ Fast, convenient installation with early strength gain „ Withstands a wide range of chemicals „ Non-shrink and hence ensures complete surface contact and bond „ Low creep characteristics under sustained loading Description Conbextra EP10 for grouting gaps ranging from 0.25 mm - 10 mm. It is an all liquid system consisting of a base and hardener. Technical Support Parchem offers a comprehensive range of high quality, high performance construction products. In addition, Parchem offers technical support and on-site service to specifiers, end-users and contractors. Dimensional Stability For the grout to effectively transfer load from the base plate to the supporting structure it is essential that the grout maintains intimate contact with the base plate. The area of contact between the grout and the base plate is measured as the ‘effective bearing area’ (EBA). In order to maintain an even load distribution throughout the grout it is necessary to attain as high as possible EBA. The Conbextra EP10 has been designed so it achieves the best possible EBA. Chemical Resistance Conbextra EP10 is resistant to oil, grease, fats, most chemicals, mild acids and alkalis, fresh and sea water. Consult Parchem Technical Services when exposure to solvents or concentrated chemicals is anticipated. Properties The following results are typical for the hardened grout at 20°C. Test method for: Typical result EP10 Density (kg/m³): 1060 Compressive strength (MPa) 1 day: 57 3 days: 66 7 days: 83 Indirect Tensile strength @ 7 days (AS1012.10-2000) 15 MPa @ 23°C Modulus of Rupture @ 7 days (Flexural Strength) (AS 1012.11- 2000) 30 MPa @ 23°C Note: Compressive strengths stated above were measured using cube samples. Test results obtained will vary if testing is carried out to an alternative standard or sample dimensions are used. Pot life Ambient temperature affects the time for which bulk material will remain fluid. Typical values in minutes are: 10°C 20°C 30°C 40°C Pot Life 40 20 10 - Exotherm All epoxy systems will develop a temperature rise on mixing. Its extent will be a function of the volume to surface ratio, the ambient temperature, as well as the mass and thermal conductivity of the surrounding materials.
