 Concrete floor cracks on asphalt concrete pavement has a length more than 30 meters long longitudinal crack, how to deal with, how to deal with transverse cracks, pits on how to deal with Henan Meeting to bridge the professional pavement / bridge repair production of new materials and comprehensive solution formula scheme service integrator, is quick passage of road patching industry leader! crack concrete floor dusting Putty, first determine the level of the concrete floor cracks appear, 1, if the width is less than 1mm, Henan Department can use Bridge Technology Co BC type repair materials were pouring process can be. 2 If the width is greater than 1mm, can use Henan Road and Bridge Department of Science and Technology Co., Ltd. of SC type slotting process pavement repair materials from sand parking lot concrete floor, grooving width and depth according to road class needs. If construction: Cracking a general road because cement hydration heat caused by too much, and some grading and aggregate nature, and if there is no reflection of alkali aggregate gradation is reasonable, that is cement factor and see not early strength cement concrete floor dusting, as early strength cement early hydration heat-largest cement ground from the sand processing, easy to make concrete cracking. Processing method is to first look at the crack is not affect the structural safety, does not affect the mud pouring water on it. Must fight off the impact from the new concrete. How do the concrete floor cracks ground cracks. To Zezheng. How do produce concrete repair concrete reasons for the appearance of quality defects (Henan Meeting to bridge Detailed) concrete itself is a multi-phase (volume 2 to 5 percent from gas, liquid 13 to 18 percent, a solid phase 77 to 85%), porous uneven (gel pores, holes between layers, pores, holes and cracks in thick bubbles, etc.) there is an internal native defects discontinuities, in addition, since the fluctuations in raw material quality used, the measurement error is sufficiently stir easily understood so that the new fresh concrete segregation occurs, poor bleeding, dry, compacted workability and other characteristics; and because of improper construction process deviations template and steel production, as well as casting, vibration, molding, maintenance and other construction operations, can be cause the appearance quality flaw cast structure.
