CGM high-strength non-shrinkage grouting material why bad side, roots rotted

CGM high-strength non-shrinkage grouting material construction CGM high-strength non-shrinkage grouting material 'bad' and 'roots rotted' flat-fell seam is mainly due to the template is not strict, juncture place check pulp is bad, vibrating CGM high-strength non-shrinkage grouting material surface caused loss of slurry. Slurry is fewer edges appear 'flash', honeycomb pitting surface slurry leakage is serious. Precaution: (1), the joint article stick rubber sponge or geotextile check pulp, with steel plate and rubber layering check pulp; 2, flat-fell seam on both sides of the vibrator when start up in sync. Repair methods: less slurry leakage repair according to piping, slurry leakage serious when repair according to treatment method of the honeycomb. Roots will rot in loose concrete and weak grain chisel, after washing clean, mold, special grouting material filling sealed, and compacted.
