CGM - Four high-strength non-shrinkage grouting material construction scheme

CGM - High-strength non-shrink grout material CGM - 4 CGM high-strength non-shrinkage grouting material manufacturer - 4 4 scheme CGM high-strength non-shrinkage grouting material construction - Four high-strength non-shrink grout material characteristics: 1, early strength, high strength 1 day 20 mpa or higher compressive strength; 3 days compressive strength of 30 mpa or greater; 28 days compressive strength 55 mpa or greater. 2, slightly swelling based, the close contact between the device and no contraction after the second grouting. 3, their high fill all voids Collins, to meet the requirements of the secondary grouting equipment 4, segregation resistance to overcome the water added in the field use for partial segregation phenomenon, as a result of more. 5, cracking resistance because of uncertainty in the field use, environmental factors such as temperature uncertainty and curing conditions crack phenomenon. 6, strong durability by fatigue test of millions of times 50 times of freeze-thaw cycle test intensity has no obvious change. In the oil immersion strength increased significantly after 30 days. 7, winter construction allowed in - Outdoor construction under 10 ℃ temperature. CGM - 4 high-strength non-shrink grout material USES: 1, used for equipment foundation secondary grouting. 2, used in anchor bolt anchorage and buried steel plant. 3, strengthening and repairing concrete structures.
