绿色自密实粉煤灰混凝土特性实验研究

The experimental research on green self-compacting fly ash concrete characteristics

通过对粉煤灰不同掺量的试验研究,测定其自密实混凝土的坍落流动性、保水性、粘聚性等工作性能指标和抗压强度、抗弯强度等力学性能,从而确定粉煤灰在自密实混凝土中的最佳掺量,探讨了在最佳掺量下自密实混凝土所具有的特性,为绿色自密实粉煤灰在实际工程中的应用提供相应的理论指导及技术支持。

Through the experimental research on fly ash different dosage, this paper determined the slump fluidity, water retention, cohesiveness and other work performance indexes and compressive strength, flexural strength and other mechanical properties of self-compacting concrete, there- by determined the best dosage of fly ash in self-compacting concrete. Discussed the characteristics of self-compacting concrete in best dosage, pro- vided corresponding theoretical guidance and technical support for the application of green self-compacting fly ash in practical engineering.
