| Abstract: | In this article, the author trys to probe into the possibility of the early stage power survey of major diameter concrete-pouring stakes, its testing method and the calculation of the concrete ripeness of the stake body . According to experimental data, he also puts forward the calculating method and practical calculation formula of the concrete quasi-compressive resistance on the basis of the early ripeness of concrete and the speed of elastic waves. |
