Applications 1, beam prestressed pipe grouting; 2, equipment foundation, bolt and other components grouting; 3, nuclear shell filling; 4, loose concrete, repairing cracks and holes and other defects. Second, the performance indicators of project performance test standard test methods of 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 10 ~ 17 JTG / TF 50-2011 Appendix C3 30min 10 ~ 20 60min fluidity fluidity 10-25 bleeding rate (%) 24h liberal bleeding rate 0 JTG / TF 50-2011 Appendix C4 3h wire 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 (%) 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 Act)" (GB / T 17671) 7d ≥40 28d ≥50 flexural strength (MPa) 3d ≥5 7d ≥6 28d ≥10 corrosion of steel without corrosion effect "concrete admixture" (GB8076) Third, the construction method, must be tested prior to use with cement were to determine the optimal ratio, H-60B Recommended dosage is mixed with 10.0% in the water-cement ratio 0.26-0.28%. 2, mixing: speed should not be less than 1000 rpm / min high-speed mechanical mixer mixing, mixing order: first the water was added to the appropriate scale, open mixer, even adding grouting agents, and even adding cement; finished adding all the powder After stirring for 3-5 minutes and then grouting 3, grouting: grouting soon as possible after mixing, grouting should take the usual methods. 4. Cleaning: Clean all water construction tools and equipment. 5. protection measures: the construction process to wear protective gloves and goggles.
