TD-C11 prestressed pipe pressure slurry (Passenger Dedicated prestressed pipe pressure slurry) I. Features: 1. Good fluidity, high strength, no bleeding, no stratification. 2. durability, based inorganic grout material, no aging, no corrosion of steel, durable and strong. 3. grouting have full early strength, micro-expansion properties. The product has high filling properties, grouting construction of one-time, non-porous dense slurry pipeline. 5. prestressing steel does not rust, and concrete bonded firmly. 6. Easy to use, water can be used directly. Second, the technical indicators :( Executive Standard: TB / T3192-2008) Third, use: 1. tendons production, Anchorage, fixtures, installation, pre-stressing, grouting, etc. should meet the design requirements, in line with Interim technical conditions prescribed PDL Precast Prestressed Concrete Beam. 2. prestressed pipe pressure slurry mixing the grout reference cement ratio of not more than 0.34, the proposed water-cement ratio 0.29-0.32, according to tests required to determine the actual water-cement ratio. Added to the actual mixing water in a blender for 80% -90%, starting with a stirrer, a uniform slurry was added to all the pressure, slow stirring 2min, then with rapid stirring 1min, add the remaining 10% -20% of the mixing water and continue stirring 1min. 3. The slurry was stirred to push into the bore from the duration, depending on the temperature conditions, are generally within the range 30-45min. The slurry pressure injection process before use and should be continuously stirred. Fourth, Cautions 1. grouting slurry temperature should be maintained at between 5 ℃ -30 ℃, or should take steps to meet the criteria. 2. prestressed pipe pressure slurry, water weighing accuracy, and in strict accordance with the determined water-cement ratio, not free to adjust the amount of water. V., packaging and storage 1. The product is plastic woven (plus lining), net weight 25 kg / bag. 2. To be stored in dry and ventilated room. 3. The shelf life of six months.
