摘要

The new back up berm recently completed immediately downstream of the Saluda dam in South Carolina, USA, contains 990 400 m~3 of RCC, 79 000 m~3 of conventional concrete, and 2.5 x 10~6m~3of rock. Contractor, Barnard Construction Company Inc had previously completed the trial sections for the project using Aran continuous mixing plants, operated by a sub-contractor. During the bid preparation for the main dam project, Barnard engineers investigated various options for cooling and mixing the RCC, including use of the large tower-type batch plants with ice cooling as used at Olivenhain dam. According to M. Killian of Barnard, the combination of modern Aran Modumix II-3 continuous mixing plants and a continuous cooling system, offered by Coldcrete Inc, offered advantages compared with conventional batch plants on both capital and unit mixing cost. The choice allowed Barnard to be very competitive and to build a high quality dam efficiently and to schedule. Savings on foundations, erection and demobilization, and wear costs compared with batch plant alternatives were substantial, Killian said.

Killian所说，Coldcrete Inc.提供的现代Aran Modumix II-3连续混合设备和连续冷却系统的组合在资本和单位混合成本上均比传统的分批设备更具优势。这一选择使Barnard极具竞争力，并能高效，按计划建造高质量的大坝。基利安说，与批量生产的替代品相比，节省了地基，架设和复员以及磨损成本。
