 How do crack factory floor? Ground from cracks, big problems, ah, what can remedy the situation? Causes of the causes of the concrete floor :( Henan Meeting to bridge Detailed) (1) cement strength rating is too low, resulting in less than the design strength of mortar requirements; plus excess water (2) cement mortar uneven mixing or agitation; (3) concrete floor surface pressure light weight often enough or untrue; (4) the surface of cement mortar or a bad time to grasp the calender in the final setting after the calender. (1) road drainage system is unreasonable: Cellular concrete reason Prevention (BC cement pavement repair materials) constitutes the main reason for these diseases form a pockmarked face. Cement concrete road, the first thing to think about the question that is on the water control. If the drainage system shortcomings, so this should be drained of water, and many can not efflux stranded on the road, bound to constitute a surface water infiltration to the roadbed, some fragile cement pavement subgrade strength from the sand causing agents, thus showing a large area severe diseases. (2) road construction is unreasonable. Most cement concrete road choice of cement, lime stable roadbed soil paving materials. Maintenance work on the basis of experience gained over the years, the use of cement, lime stable soil cement concrete pavement as the underlying has many shortcomings. Due to poor water smooth surface of the kind of information from the sand, after being soaked in water once a traffic load of duplicate results, will soon constitute a squirt mud, concrete pavement repair materials from sand bottom underrun forming plate, resulting in channel plate Part discontinuity, causing road damage. (3) along with economic development, overloading, rendering many overweight vehicles, further exacerbating the damaged concrete pavement speed.
