| 摘 要： | 通过实验室内试验和现场试验，选择和改进了ＲＣＣ配合比；比较了ＲＣＣ工艺和ＲＣＤ工法。实验表明：ＨＲＣＣ要求最小胶凝材料用量１８０ｋｇ／ｍ＾３；其技术性能接近或优于同级常 态混凝土；施工接缝抗剪强度较高，即使夏季施工也不例外，因此，ＨＲＣＣ满足龙滩２００ｍ级高坝的要求。

| Abstract: | The paper describes that the mix proportion and technical Perarneters of RCC are selected and im-proved through the laboratory tests and field experiments. The RCC technique and RCD methed are compared.The tests show that it is necessary for HRCC technology that the lowest unit cementitious content is 180 kg/m;The charateristics are near or suPerior to that of conventional concrete with the sarne grade, and the joint shearstrength is higher even if Sumrner construction. Therefore the HRCC technology is satisfied for requirements ofLongtan darn of 200m high. |
