巴基斯坦阿莱瓦水电站工程混凝土碱硅反应的试验研究及预防

Test Study and Prevention of Concrete's Alkali-silicon Reaction for Allai Khwar Hydropower Project in Pakistan

通过对巴基斯坦阿莱瓦水电站工程混凝土潜在的碱硅反应产生的机理和条件进行了相关的论述和试验研究,并从混凝土施工配合比及施工工艺等方面进行有效的控制和预防,所浇筑混凝土结构没有发生碱硅反应的开裂破坏,混凝土结构是安全的,确保了工程质量。

The paper studies and discusses mechanism and conditions leading to potential Alkali-silicon reaction of concrete to be used for construction of Allai Khwar Hydropower Project in Pakistan. Through site tests and studies, it is found that quality of concrete construction of the project is able to be ensured by taking effective control and preventive measures for mix design, construction workmanship, etc.
