H-60B prestressed pipe pressure slurry This product is fully satisfied "JTG / T F50-2011" highway bridge construction technical specifications "," high performance prestressed pore filling material requirements. I. Applications 1, beam prestressed pipe grouting; 2, equipment foundation, bolt and other components grouting; 3, filling the case of nuclear power plants; 4, loose concrete, repair cracks and holes and other defects. Second, the performance indicators Project performance test standard test method for water-cement ratio (%) 0.26 - 0.28 "cement standard consistency water, setting time and soundness test method" (GB / T 1346) setting time (h) the initial setting ≥5 Final setting ≤24 fluidity (25 ℃) (s) initial fluidity of 10 ~ 17 JTG / TF 50-2011 Appendix C3 30min 10 ~ 20 60min fluidity fluidity of 10 to 25 bleeding rate (%) 24h free bleeding rate 0 JTG / TF 50-2011 steel appendix C4 3h bleeding rate 0 JTG / TF 50-2011 Appendix C5 pressure bleeding rate (%) 0.22MPa (channel vertical height ≤1.8m) ≤2.0 JTG / TF 50-2011 Appendix C6 0.36MPa (channel vertical height> 1.8m) ≤2.0 free expansion rate (%) 3h 0 ~ 2 JTG / TF 50-2011 Appendix C4 24h 0 ~ 3 filling degree qualified JTG / TF 50-2011 Appendix C7 compressive strength (MPa ) 3d ≥20 "cement mortar strength test method (ISO method)" (GB / T 17671) 7d ≥40 28d ≥50 flexural strength (MPa) 3d ≥5 7d ≥6 28d ≥10 corrosion of the steel for non-corrosion "Concrete admixtures" (GB8076) Third, the construction method, the cement must be tested prior to use to determine the best ratio with, H-60B Recommended dosage is within the mixed 10.0%, water-cement ratio 0.26-0.28%. 2, mixing: Speed ??should not be less than 1000 rpm / min high-speed mechanical stirrer agitation at the following order: first the water was added to the appropriate scale, open mixer, a uniform grouting agent is added, and then even the cement; all the powder material into finished After stirring for another 3-5 minutes grouting 3, grouting: grouting soon as possible after mixing, grouting should take the usual methods. 4, clean: clean water for all the construction tools and equipment. 5. protection measures: the construction process to wear protective gloves and goggles.
