摘 要:以中国建筑玉树援建项目为依托,开展了高原高海拔地区普通强度等级混凝土的高性能化的研究工作。从混凝土原材料、工作性能、耐久性能等方面进行了混凝土配合比的设计;从混凝土原材料质量、原材料供应、坍落度控制、生产设备功率等方面分析了混凝土生产中应注意的事项;根据当地气候条件、环境条件、机械设备条件、人员身体条件等影响因素,对混凝土运输中应注意的事项进行了说明。
Abstract:Relying on Yushu reconstruction projects in Qinghai Province, the mixture design, production and transportation of concrete in the plateau high altitudes are carried out. From the concrete raw materials, work performance, durability and other aspects, the mix proportion design of concrete is proceeded. The attention issues of concrete production is analyzed from the aspects of concrete raw material quality, raw material supply, slumping control, production equipment power. According to the local climatic conditions, environmental conditions, equipment conditions, body conditions and other factors, the concrete transportation matters needing attention are described.
