Bridge bearing grouting material standards

Bridges grouting, grouting material bearing bridge bearing grouting material standards: the performance indicators meet the beijing-shanghai high-speed railway and the implementation details of high performance concrete applied to the bridge of passenger dedicated line pot rubber bearing interim technical conditions, such as national and industry standards and technical requirements. Technical service - - 15838304411. Typical material: M50 harsh without shrinkage of mortar and M50 liquidity without shrinkage of mortar. 1, bridge bearing grouting material has excellent liquidity, gravity leveling, without vibration, pressure, construction speed is quick and convenient. 2, high hours late strength, high strength, not shrink. According to the different construction temperature, can obtain 20-2 hours 40 mpa compressive strength, flexural strength is high. 3, with micro expansion properties and excellent crack resistance. 4, to adapt to the wide temperature range and in - 5℃～- 35 ℃ under the condition without any auxiliary insulation or cooling measures can the construction. Under the condition of high temperature or low temperature, can guarantee the strength at the same time the needs of the development and construction of liquidity. 5, suitable for repair, track filling, support grouting, especially suitable for high speed railway bridge bearings or orbital filling etc. Can also be used for concrete beam local leveling or repair of the concrete pier. 6, conform to 'interim technical conditions of passenger dedicated line concrete precast beam' and 'the bridge of passenger dedicated line pot rubber bearing interim technical conditions' requirement.
