| Abstract: | The Inverted Siphon Project of the Tang River is a large-scaled river-graff-cross building of South-to-North Water Transfer. In the initial design report, fines used to make concrete is sand from the Tang River. However, after examining, it is found that the sand from the Tang River is based-activity. To assure the quality of the concrete, the construction administration organized related experts several times to analysis, argue, and test. At last, it is changed to use sand from the Sha River to make concrete. |
