摘要
某水库工程机制山砂石粉含量最高值达25%,超过技术规范标准,并且母岩为白云岩成分,在大体积RCC中应用是首例,无参考经验可以借鉴。通过白云岩石粉在贵州某水库高性能碾压混凝土中的实际应用,对其进行试验研究,对现行规范的石粉用量范围进行突破,获得白云岩石粉含量对强度等性能的影响规律,确定石粉含量的最优范围。
The mechanism of a reservoir engineering in Guizhou mountain sand powder content peak of more than 25%,more than technical regulation standards. The mother rock of high performance roller compacted concrete RCC used in a reservoir project in Guizhou province is dolomite,and the parent rock of dolomite application is the first in the mass RCC,no experience can be reference. Through the application of dolomite powder in high performance RCC in Guizhou reservoir,experiment and research on it is done,and breakthrough is made to the current standard of stone powder consumption. The influence law of dolomite powder content on the strength is obtained and stress-strain curve,by which the optimum range of rock powder content is determined.
