Abstract：
During floor construction of a large factory building, laser super-flat technique was adopted to not only guarantee the construction quality, but also accelerate the construction schedule; special steel fiber reinforced concrete admixed in the floor substratum could improve the crack resistance of floor; the floor surface was sealed and consolidated by using corundum grain to increase the dustproof and cleaning capacity of the floor and to reduce the service and maintenance cost. These construction techniques could reduce working intensity, improve construction quality of large factory building floor, reduce material consumption, energy consumption and air pollution, increase productivity and satisfy the requirements of green construction.
