结合渡口坝工程实际,设计出满足大坝各部位混凝土技术指标要求的配合比。根据大坝各部位对混凝土性能的不同设计要求,将大坝划分为5个系列。对水泥、粉煤灰、外加剂、骨料等原材料进行了品质鉴定,并在此的基础上选择合适的配合比参数,给出推荐配合比。性能指标试验结果表明,推荐配合比混凝土满足设计要求。
Combined with the actual project of the dam, designed to meet the technical requirements of various parts of the dam concrete mix ratio. According to the dam different parts of the concrete performance of different design requirements, the dam is divided into five series. The qualities of raw materials such as cement, fly ash, admixture and aggregates were identified, and on the basis of this, the appropriate compounding parameters were selected to give the recommended compounding ratio. Performance indicators Test results show that the recommended mix of concrete to meet the design requirements.
