Supports high-speed rail grout grouting material manufacturers

Railway bridge bearing grout, grout bridge strengthening, bolt grouting material, high-speed rail grout grouting material bearing I. Introduction: a special railway carriage grout mortar is a high-quality cement-based composite materials, the product uses a variety of high performance additives, particularly smooth surface after hardening, to overcome the traditional mortar uneven ﹑ ﹑ cracking peeling from powder shortcomings, with self-leveling, easy high early strength non-shrink ﹑ ﹑ ﹑ high-strength and high wear-resistant construction and other characteristics. Second, the performance characteristics: its performance in line with "the Beijing-Shanghai high-speed railway performance concrete Shi Rules" and "Railway Bridge rubber bearing basin Interim technical conditions" national standards and technical requirements of the railway industry. Has excellent mobility, gravity leveling, no vibration, wiping pressure, the construction speed, convenience; the hour with a very high intensity, high late strength, does not shrink; depending on the application temperature for 2 hours to obtain 20- 40Mpa compressive strength, flexural strength; with micro-expansion properties and excellent crack resistance; wide temperature range to adapt, at -5 ℃ ~ -35 ℃ condition, without any auxiliary heat or cooling measures can be construction; in high or low temperature conditions, it is possible while maintaining strength development and construction needs liquidity. The main technical and indicators: No. Test Item Unit standard test results Fluidity 01 mm ≥220 318 02 30 minutes after the fluidity mm - 258 03% bleeding rate no bleeding no bleeding 04 2h compressive strength MPa - 23 05 8h compressive strength MPa ≥20 28.6 06 12h compressive strength MPa ≥25 33 07 24h compressive strength and flexural strength MPa ≥6 9 ≥40 48 08 28d compressive strength and flexural strength MPa ≥8 10.6 ≥50 62.0 09 56d flexural strength MPa ≥10 12.2 MPa compressive strength is not reduced 74 10 90d flexural strength of 12.5 MPa compressive strength is not reduced without reducing MPa 78 11 28d expansion% ≥0.1 0.2 12 Elastic Modulus GPa ≥30 32.8 Notes: 1. During the test, the water feed ratio 0.14; 2. technology based on: "Railway Bridge rubber bearing basin Interim technical conditions." Third, the application areas: adaptation to repair the track is filled, bearing grout, especially for high-speed rail bridge bearing or track such as filling. It can also be used for leveling concrete beams or concrete piers partial repair. In line with "Passenger Dedicated precast concrete beams Interim technical conditions" and "Railway Bridge rubber bearing basin Interim technical conditions" requirements. Fourth, the construction process: First, the grass-roots clean, remove floating dust, oil stains, which are not conducive to the bonding material. Before construction, grass-roots moist with tap water, we can not leave out of water pouring mortar; calculating the amount of powder and water consumption per unit of time according to the construction area, and the construction area, to ensure that the mortar leveling before losing all construction is completed; will join the stirred water bucket, then said good self-leveling material was gradually added, while stirring, until the desired material all finished, then continue stirring for 2-3 minutes, the slurry uniform, stand for 1 minute; the material is uniformly good mixing Pour a good handle on the ground, it can self-leveling; leveling construction time is preferably within 30 minutes after the construction equipment side, namely water rinse; stirring the powder, it is best to use an electric mixer with stirring, large-scale construction When advised to use a mortar mixer.
