Innovation on Commercial Concrete Floor Slab Construction Technology

Abstract:

Take Shunjing International Plaza project as an example, investigate on the status of large areas of cast-in-place pumping commercial concrete floor construction , In view of common quality defects of early shrinkage cracks, innovate pumping concrete construction technology, namely, set the sub-grid band, strictly control the quality of raw materials and the concrete mix ratio, rub repeatedly both manually and mechanically, enhance early maintenance, adopt appropriate technical intermittence process and so on, After the engineering applications, the technology had guaranteed the concrete quality smooth and dense, eliminated the early cracks of the concrete.
