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 incorporation of the product can cause moderate expansion to compensate for curing shrinkage grout or concrete produced at different times. http://www.chinasjxy.com/ [highway bridge dedicated prestressed pipe grouting agent] Features * good fluidity, high strength, no bleeding, no segregation, not hierarchical. · Micro - expansive, grouting with a full early strength, strong bond with the concrete. * With high filling property, one-time grouting construction, pipeline grouting tight non-porous. · Durability, resistance to aging, no corrosion of steel, durable strong. * Note: Easy to use, 10 percent mixed cement grouting agents into P42.5 made of micro-expansion pressure slurry can be used. ? [Highway bridge dedicated prestressed pipe grouting agent] scope pipeline grouting agent suitable for the construction of various pore filling material may be added into the grout, mortar and concrete grout material, especially for roads, bridges, nuclear power plants, etc. post-tensioned construction of major projects have bonded prestressed concrete pore grout.
