ABADUR-G3
3-COMPONENT EPOXY GROUT
DESCRIPTION
A three-component pourable, solvent free epoxy grout based on a high grade epoxy resin and specially graded aggregates. ABADUR-G3 has been designed to reach a roughly 80 percent of its maximum mechanical strength capacity at its very early ages to maintain it as useful for further applications. Once mixing, a flowable grout is produced for use in heavy duty applications and difficult conditions. This product is designed to be applicable in temperature range between +15 and +35 °C.
SURFACE PREPARATION
- 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.
- Concrete should have attained a minimum compressive strength of 21 MPa, higher strength concrete is recommended for optimum performance of grout.
- All surfaces should be dry, clean, and free from standing water, grease, curing compounds, mold oils, all loosely adhered aggregates and cement particles, etc.
- 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 until a flowing uniform grout is achieved.
- Avoid excessive mixing which will result in reduction of working time and heat generation.
APPLICATION
- 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.
- 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.
- If grouting in multiple layers, it is necessary to sprinkle a small amount of 2.5 mm aggregate over the first layer before the grout reaches its setting time. Before placement of 2nd layer brush out loose aggregates from the 1st pour. Another method is to scrabble gently the top surface and make it rough when grout reaches near to its setting time.
.
