粉煤灰掺量对自流平混凝土性能的影响

Effect of Fly Ash Proportion on Performances of Self-leveling Concrete

在分析自流平混凝土特点的基础上,根据试验数据总结出自流平混凝土中不同的粉煤灰掺量对自流平混凝土性能的影响规律。在研制过程中系统分析了流动度L与扩展度D之间的关系,建立了L-D对比曲线,形象直观地表达了砂浆的使用性和工作性,最终选出较合理的掺量范围。

An experiment was conducted to study the effect of fly ash proportion on the performances of self-leveling concrete in terms of the characteristics of self-leveling concrete. The relationship between fluidity and divergence was analysed by setting up a curve concerning fluidity and divergence, which could visually express the service performance and workability of cement mortar, thereby a reasonable fly ash proportion could be obtained.
