ABADUR-G3 LE

​SURFACE PREPARATION

• All surfaces should be dry, clean, and free from standing water, grease, curing compounds, mold oils, all loosely adhered aggregates and cement particles, etc.
• Concrete should be old enough, if it is newly placed concrete then it needs to be 28 days old and to have reached its design strength.it is also needed the substrate to have structural humidity less than 4 percent. 
• Concrete should have attained a minimum compressive strength of 21 MPa, higher strength concrete is recommended for optimum performance of grout.
• Chip the concrete surface so aggregates are exposed to ensure all laitance and weak particles are removed. Alternatively use a spray on surface retarder when placing concrete.
• Chamfer the edges of the concrete 45 degrees to 50 mm. width to avoid sharp corners which helps to reduce the potential for cracking.
• Shade the foundation from direct sunlight for at least 24 hours before grouting and 48 hours after grouting.

MIXING

• Before mixing ensure all the components are cool, shaded and dry. If not preconditioned store all components below 25°C for 24 hours before using.
• The temperature of grout, base plate and foundation are more important than the air temperature because they are directly related to the flow of grout.
• Add component A & B in a mixing vessel and mix under slow speed (RPM 400) for approximate 1 minute. Then add component C and continue mixing for about further 2 minutes until a flowing uniform grout is achieved.
• Avoid excessive mixing which will result in reduction of working time and heat generation.

APPLICATION

• Grouting operation should be done immediately after mixing completion, in less than 15 minutes. Grout should be applied continuously and from the appropriate height.
• While grouting the base plates ensure there is sufficient pressure head to maintain movement of grout.
• Base plates with a flat base pour the grout from one side through the other across the short dimensions.
• Drop pressure from a higher height may be required to fill larger dimensions and longer distances. In this case, it is recommended to use the Head Box. Head boxes are usually installed along the length and on one side of the foundation.
• the grout site should be designed in such a way that it is possible for air to escape out of the section under grout. Therefore, ensure entrapped air can escape when grouting closed areas.
• Where grout cannot flow and have smooth movement because of the length of pour pushing aids like steel chains, strips of plywood, etc. can be used.
• The base plate with anchor bolts, dowel, starter bar, etc. should be grouted first followed by the base plate.

TECHNICAL NOTES

•  The hardening reaction of epoxy grout is exothermic and increasing the temperature of the grout in the mixing vessel will lead to loss of its efficiency. Therefore, always mix the amount of components together and apply in the first minutes after mixing.
• The nature of all epoxy-based resins is such that, depending on parameters such as viscosity, temperature in the cold season, etc., they may be accidentally solidified and look like water freezing, which is called crystallization. The crystallization phenomenon in epoxy resin materials is reversible and does not affect the quality of the epoxy mixture. In case of this situation, it is necessary to place the epoxy resin at a temperature of 50°C to 70°C to fully return to the original state.

Note: In cold seasons, to stabilize the physical condition of the material, it should be stored in an environment with a temperature of 30°C for 24 hours before consumption.

• In hot weather, the temperature of the components before mixing should be between 20 and 25 degrees Celsius. Otherwise, the Pot Life will be drastically reduced.
• If the height of the place being grouted is more than 150 mm, the grouting operation should be done in several stages and in accordance with the table of environmental conditions.
• Never dilute the mixture.
• Never expose the material to direct sunlight before mixing.
• Considering the expansion joint for the epoxy grout leads to the conduction of possible stored stresses there and greatly reduces the possibility of cracking.
