| Abstract: | The cracking of concrete structures, especially floors, ca n still not be fully avoided over the world. By engineering investigation, anal ysis and in situ tests, the outcome obtained is satisfied. The authors introduc e the theoretical foundation and construction technology, wih which the early-ag e cracks and the late-age cracks of a 250,000m2 frame structure including beams , columns and floors using pumping concrete, are not appeared. |
