CGM high-strength non-shrink grout I. Features 1, the early strength, high strength, equipment installed to run the production of two one day, high flow, no bleeding, anti-corrosion 3, composite expansion double effect, precise positioning 4, the correct grouting construction technology can reach 90% of the effective bearing surface (EBA) Second, the product performance indicators CGM high-strength non-shrink grout key performance indicators (Table 1) Model CGM-380 CGM-340 CGM-300 CGM-270 fluidity ( mm) initial value ≥380 ≥340 ≥300 ≥270 * ≥650 ** 30min retention values ??≥340 ≥310 ≥260 ≥240 * ≥550 ** vertical expansion (swelling value%) 3h 0.1 ~ 3.5 24h and 3h of the difference between the 0.02 to 0.5 standard product features ultra-early-strength antifreeze corrosion resistant type of ultra high strength steel fiber compressive strength (MPa) 2h ≥15.0 1d ≥20.0 ≥30.0 ??≥10.0 ≥20.0 ≥20.0 ≥30.0 ??≥30.0 ??3d ≥40.0 ≥ 40.0 ≥15.0 ≥40.0 ≥40.0 ≥50.0 ≥50.0 28d ≥60.0 ≥60.0 ≥60.0 ≥60.0 ≥60.0 ≥80.0 ≥80.0 whether the corrosion of steel for non-bleeding rate (%) 0 l * denote slump value ** said the slump flow value; l may need to select the appropriate characteristics according to the project of CGM high-strength non-shrink grout products; l antifreeze compressive strength is measured at -10 ℃; l corrosion is suitable for coastal ports, salt, salt stains equipment foundation erosion-hit areas, secondary grouting foot steel column base. Meet JC / T1011-2006 "sulfate corrosion resistance of concrete preservatives", GB / T18736-2002 "high performance concrete with mineral admixtures" and other standards. l The above data under standard laboratory controlled conditions measured; l unit dosage: about 2200kg ~ 2400kg / m3; a: CGM for winter construction of high-strength non-shrink grout shall comply with the provisions of Table I and Table II. CGM antifreeze for construction in winter when the high-strength non-shrink grout performance indicators (Table II) specified temperature (℃) compressive strength ratio (%) R-7 R-7 + 28 R-7 + 56 -5 ≥20 ≥ 80 ≥90 -10 ≥12 Note: 1, R-7 indicates a negative temperature curing 7 days compressive strength of specimens with standard curing ratio 28 days compressive strength value of the specimen; 2, R-7 + 28, R-7 + 56 denote negative temperature curing 7 days 28 days and negative turn standard curing temperature curing 7 days turn standard curing 56 days compressive strength value of the specimen and the ratio of the standard 28 days of curing specimens compressive strength values. 3, the construction of a predetermined temperature lower than the lowest temperature 5 ℃.
