Henan prestressed pipe pressure slurry prestressed pipe pressure paste manufacturer henan prestressed pipe pulp manufacturers bridge tunnel grouting material, pipe grouting seam an agent, hole size, bearing no shrinkage grouting material corrosion resistance of prestressed duct grouting beautiful seam an agent, pipe grouting material of railway Bridges, non-shrinkage grouting material and grouting support material, product introduction: railway passenger dedicated line pipe grouting concrete beams seam an agent ( Pressure slurry) The organic polymer and inorganic high performance functional materials is given priority to, functional material compound and into a new and beautiful seam an agent. Products with water reducing, enhance, protect plastic, micro expansion and multiple functions such as low exudation in mixed with cement or concrete, can not only under the precondition of low water-binder ratio greatly improve the fluidity of slurry pressure and can effectively solve the cement, concrete such multiple, multicomponent, non-uniform mixing system of the contradiction between high liquidity and segregation resistance, reduce bleeding phenomenon at the same time, this product contains the early expansion ( The aluminum powder) Late and expansion of components, to compensate for the material in different shaping contraction or concrete. Period of contraction. Second, the product features: good prestressed pipe pressure slurry flow, high strength, no bleeding, no segregation, no separation; Micro expansion feature, grouting with full early strength, strong and concrete binding; With high filling, can one-time grouting construction, pipe grouting closely without pore, good durability, ageing resistance, no rust steel, durability; High mechanical properties, flexural and compressive strength were significantly higher than standard requirements; Chloride ion content is less than 0. 1%, sodium sulfate content less than 1%; Easy to use, grouting the seam an agent 8 ~ 12% mixed with cement mixed with common micro expansion grouting material can be used. Three, scope of application: prestressed pipe grouting seam an agent ( Pressure slurry) Are suitable for all kinds of channel construction of grouting material, can be added to the slurry, cement mortar and concrete grouting material, especially suitable for roads, Bridges, nuclear power plants and other large engineering of bonded post-tensioned prestressed concrete construction of the duct grouting materials. Execution standard JC/T986 - 2005 'cement grouting material specifications' (JGJ/T70 - 2009 'basic performance test method standard building mortar' TB/T3192 - After 2008, 'railway tensioning prestressed concrete beam pipe grouting technology conditions' pipe grouting seam an agent ( Pressure slurry) Beauty is a kind of powder add seam an agent, when at a certain ratio ( 10% of the cement) Added in the cement, water can form a kind of mixed with shrinkage compensating, thixotropic slurry injection should add the seam an agent has, corrosion, swelling, the effect of resistance to rust, etc, makes the control of the ratio of water to cement in 0. The strength of the 30 or so obtained after grouting, high. Scope of application: pipe grouting seam an agent can be used for prestressed bridge anchoring and grouting hole, to prevent the groundwater corrosion of reinforcing steel bar, As a stone anchorage) And steel strand ( Such as tensile cables) Because of its thixotropy, more adapted to the ground grouting. From the application point with pregrouting and after grouting bolt and steel strand. Henan prestressed pipe pressure paste manufacturers WWW. godjc。 com
