大掺量粉煤灰技术在混凝土中的推广应用

摘要

结合工程实践,阐述了大掺量粉煤灰混凝土的优良性能,分析了大掺量粉煤灰技术对外加剂的要求,试验结果表明,大掺量粉煤灰混凝土的工作性、力学性能良好;施工配合比使混凝土既能满足耐久性要求,又能满足低成本要求,在工程施工中必须采用大掺量粉煤灰技术。%Combining with the engineering practice,this paper elaborated the fine performance of large volume fly ash,analysed the request of large volume fly ash to admixture,the test results showed that,the workability,mechanical performance of large volume fly ash was good,the construction mix proportion of concrete could meet the durability requirements,and also could meet low cost requirements,we must take large volume fly ash technology in engineering construction.
