The problems in the concrete pouring epoxy grout repair available

1, honeycomb: why is the concrete material under a thick, vibrating false or leakage of vibration; There is crack template slurry erosion; Steel bar is dense and concrete slump for small or large stones; Foundation, columns and walls of the lower step casting ensued after upper keep pouring concrete, so that the upper concrete mortar poured out of the bottom and cause the root. 2, exposure: the reason is reinforced cushion block displacement, spacing is too large, leakage, reinforced against template exposure or false may also appear at the bottom of the beam and plate vibration starts exposure. 3, pits: template surface is not smooth or template wet enough, concrete component surface adhesion easily cause peeling pits on the template. 4, holes: the reason is stuck at the site of the steel bar is dense concrete, without the upper vibrating keep pouring concrete. 5, gaps and layers: the construction joints of cleaning not net or not watering the bottom slurry causes such as gap, mezzanine. 6, beam and column section size deviation at junctions is too large, the main reason is that poor template column joint stiffness. 7, smooth cast-in-place floor and the stairs deviation is too big, the main reason is not serious with trowel smooth surface after concrete pouring
