本文提出了两项试验成果:一项是三峡坝址附近三个料场(朱家沟、白崖山和下岸溪)的人工砂的质量鉴定成果;另一项是以这些人工砂为细骨料的混凝土的性能试验成果(以基坑处的闪云斜长花岗岩为粗骨料)。试验结果表明:三峡料场的人工砂的质量均符合坝工混凝土用砂的要求;按照设计控制条件拌和的混凝土,其性能也都符合设计要求。
This paper presents two experimental results: one is the identification of the quality of artificial sand in the three material silos (Zhujiagou, Baiyashan and Xiayanxi) near the Three Gorges Dam site; the other is that the artificial sand is fine bone Experimental results of the performance of the expected concrete material (to the pit at the Shiyun plagioclase granite coarse aggregate). The test results show that the quality of the artificial sand in the Three Gorges stockyard meets the requirements of the dam concrete. The performance of the concrete mixed with the designed control conditions also meets the design requirements.
