H-60 prestressed pipe grouting agent First, the product scope of application of this product is suitable for post-tensioning grout, mortar and concrete grout material, particularly suitable for rail roads, bridges, nuclear power plants and other large projects are bonded prestressed concrete pore filling material construction. Second, product characteristics 1, good liquidity, no bleeding, no stratification; 2, grouting full early strength, micro-expansion; 3, one-time grouting construction, non-porous dense slurry pipeline; 4, prestressed steel does not rust, and concrete bonded firmly; Third, performance test based on the experimental test data :(: After TB / T3192-2008 Railway tensioned prestressed concrete beam pipe grouting technology conditions) Inspection Item Unit Performance / setting time early Ning h: min ≥4h / Final setting h: min ≤24h / out machine fluidity of 14 to 22 seconds / 30 minutes fluidity of seconds ≤30 / liberal bleeding rate (24h)% 0 / capillary bleeding rate (3h, 23 ℃)% ≤0.1 / pressure bleeding rate 0.22MPa% ≤3.5 ≤1.8m 0.36MPa channel tunnel vertical height vertical height> 1.8m filling degree / qualification / 7 day strength and flexural strength MPa ≥6.5 / compressive strength ≥35 / 28-day strength flexural strength MPa ≥10 / compressive strength ≥50 / 24h free expansion% 0-3 / corrosion of the steel bar / no rust / gas content% 1-3 / chloride ion content% / / alkali content% / / Note: cement PO 42.5R cement content of 10% in the water-cement ratio of 0.33 IV trial with former construction methods to determine the optimal ratio of 1. Use recommended dosage is 10% -12% water-cement ratio 0.30-0.33. 2. Mixing: generally the most suitable mixing order are: water → Cement → pipeline grouting agent; such as the use of mechanical agitation method generally stirring, then stirred for an appropriate extension of time to ensure that the components of the grout evenly dispersed. 3. Casting: After stirring pouring as soon as possible should take the usual method of pouring or pumping to ensure continuous placement. 4. Conservation: pouring over the area if it is exposed, maintenance materials should be used with wet sacks conservation or conservation.
