摘要
本文结合寒区水电工程试验检测数据,从混凝土热力学、物理学、配合比、理化性能等角度进行试验论证,提出凝灰岩粉可以替代全部或部分粉煤灰用于北方寒区水工混凝土,并结合现行规范提出相应的技术要求,可为有效解决粉煤灰替代问题提供数据参考。
In this paper, combined with the test and detection data of hydropower engineering in cold areas, from the perspectives of concrete thermodynamics, physics, mix ratio, physical and chemical properties, etc., the paper proposes that tuff powder can replace all or part of fly ash for hydraulic concrete in cold areas in north China, and puts forward the corresponding technical requirements combined with the current norms, which can provide data reference for effectively solving the problem of fly ash replacement.
