Bridge pore filling material 1

Bridge pore filling material, pipe grouting agent, duct grouting agents, non-shrink grout bearing corrosion prestressed Duct Grouting agents, railway bridges pipeline grouting material, non-shrink grout, grouting material bearing duct grouting agent (press slurry) is a powdery additive, when a certain proportion (accounting for 10% of cement content) being added to the cement, mixed with water will form a kind of compensatory shrinkage thixotropic slurry injection. The high-efficiency water reducing additives, corrosion resistance, expansion, rust and other effects, the water cement ratio control in about 0.30 to obtain high strength after grouting. I. Introduction: Railway Passenger Dedicated Line concrete beam duct grouting agent (pressure slurry) is a high-performance functional materials, mainly inorganic, and organic polymer composite materials made of a new type of functional additive. Products with high water reduction, enhancement, protection molding, micro-expansion and low bleeding and other multiple effects, mixed with cement or concrete, not only can greatly improve the fluidity of the slurry pressure than the premise of low water glue, and can solve the contradiction of cement, concrete such items, multi-component, non-uniform mixing system with high mobility between segregation resistance, greatly reducing the bleeding phenomenon. At the same time, the product contains the early expansion of (non-aluminum) and post-expansion component to compensate for material shaping shrinkage or contraction of concrete produced at different times. Second, the product features: Product fluidity, high strength, no bleeding, no segregation, not hierarchical; micro-expansion characteristics, grouting with a full early strength, strong bond with the concrete; filling with high resistance, one-time press Pulp construction, pipeline grouting close nonporous; durability, resistance to aging, no corrosion of steel, rugged durability; high mechanical properties, flexural and compressive strength are significantly higher than the standard requirements; chloride ion content of less than 0.1%, sulfuric acid sodium content of less than 1%; easy to use, grouting agent 8 to 12% incorporation of ordinary cement mix made from micro-expansion grouting material can be used. Third, the scope: duct grouting agent (pressure slurry) applies to the construction of various pore filling material may be added into the grout, mortar and concrete grout material, especially for post-tensioned roads, bridges, nuclear power plants and other large projects There are construction bonded prestressed concrete pore grout. Implementation of standards JC / T986-2005 "cement-based grouting material" JGJ / T70-2009 "building mortar basic performance test method standards" TB / T3192-2008 "after railway tensioned prestressed concrete beam pipe grouting technology" The main technical Specifications: Test items index setting time, h initial setting and final setting ≥5 ≤24 fluidity, s the machine 10 ~ 17 30min fluidity fluidity bleeding rate of 10 to 20,% 3h capillary bleeding rate 0 24h free bleeding rate 0 pressure bleeding rate,% 0.22MPa ≤2 0.36 MPa ≤2 compressive strength, MPa 7d ≥40 28d ≥50 flexural strength, MPa 7d ≥6.5 28d ≥10 Application: Duct Grouting agents can be used prestressed bridge tunnel anchoring and grouting to prevent groundwater corrosion reinforcement (such as stone anchor) and strand (such as pre-pull cable). Because of its thixotropic, more adapted to the grout off the ground. From the application divided into pre-and post-grouting and grout anchor strand.
