Passenger railway bridge pot rubber bearing grouting material research and application

Passenger railway bridge pot rubber bearing special grouting material is usually for passenger dedicated line bridge pot rubber bearing, special grouting material is adopted by the cement but some deficiencies in the actual use, but on the market at present is a kind of high performance polymer modified cement grouting material, by high strength cement composition, super plasticizing components, components of expansion, optimizing Gao Qiangwei aggregate composition and some trace of modified components in appropriate proportion common grinding. Its reaction with water to generate a large number of expansion of mineral - Hydrated calcium sulphoaluminate, thereby realize the material itself without shrinkage; At the same time the material has greater liquidity, good workability, can their leveling, operation time is long, and the finished surface smooth level off, overcomes the traditional mortar produced by uneven, crack, flake, powder shortcomings and so on. Its performance fully meet the passenger railway bridge pot rubber bearing interim technical conditions 'requirement. Hotline - 15838304411. Passenger railway bridge pot rubber bearing special grouting material scope of application: this product is mainly used for repair, bridge bearings anchor grouting, rail anchor grouting, etc. , especially suitable for high speed railway, pedestal grouting of passenger railway, highway, etc. Passenger railway bridge pot rubber bearing special grouting material product advantages, good liquidity, 1 in the case of low water cement ratio, of great fluidity, can be fully populated perfusion space, and implement their peace since the secret. 2, micro expansion expansion: no shrinkage populated areas; To ensure seamless bonding place, not loose, make the load function effectively passed to the base. 3, early strength, high strength, compressive strength is greater than 1 day 40 MPa, more than 60 MPa, 28 days later with high intensity and fail. 4, stable performance, completely cured grouting material, oil and other acid and alkali corrosion resistance. 5, good durability, inorganic material, there is no aging, the steel bar corrosion, durability, used for surface wearability. 6, low construction: negative temperature under low temperature and negative temperature strength still have larger growth, effectively solve the winter construction problems such as 7, easy to use: after the finished bag opening water mixing can be used in the site.
