CGM grouting material number of models

I. Introduction 13520557496 Li CGM early strength bearing grouting material is industry-leading products, it is reasonable fraction of high strength aggregate of aggregates, high strength cement as binding agents, polymers as toughening agent, combined with high flow, micro-expansion, anti-segregation, cracking and so additives, admixtures and other precise ratio of professional production from the dry mixture. CGM early strength bearing grouting material used in railway bridge bearing installation of high-quality cement-based composite materials. Because it uses a variety of high-performance additives, especially after the completion of the surface smooth. To overcome the traditional mortar uneven, cracking, spalling and other shortcomings, with self-leveling, high early strength, high strength, non-shrink, high wear resistance and construction and other convenient features. Its performance indicators 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. It has formed a prefabricated beams, cast beams, large bridges (type) and other types of products, and the formation of construction techniques and ancillary equipment in winter -10 ℃ ~ -20 ℃ conditions. For users to work in all weather conditions. Second, the main characteristics of excellent fluidity, gravity leveling, no vibration, wiping pressure, the construction speed, convenience. Hour with a very high intensity, high late strength, not shrink. Depending on the application temperature, two hours to get 20-40Mpa compressive strength, flexural strength. A micro-expansion properties and excellent resistance to cracking. Adapt to a wide temperature range, at -5 ℃ ~ -35 ℃ condition, without any auxiliary heat or cooling measures can be construction. At high or low temperatures, can simultaneously ensure the strength development and construction needs liquidity. Adapt to repair the track 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 Third, the construction method of 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. Calculate 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. Water was added to the mixing 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 mixing evenly filtered into the ground and handled well, can be self-leveling. Leveling construction time is preferably within 30 minutes to complete, after the construction equipment side, namely water rinse. While stirring the powder, it is best to use electric mixer gun stirring, use a mortar mixer when large-scale construction. See construction technology and construction technology in winter I provide.
