高掺量粉煤灰混凝土含气量试验研究

Experimental Research about Air Content of High Fly-ash Content Concrete

为研究区高掺量粉煤灰混凝土性能,采用质量法完成了42.5硅酸盐水泥混凝土不同粉煤灰掺量(0%、10%、20%、30%和40%)的配合比设计,通过实测掌握了混凝土拌合物的含气量随掺量和水胶比的变化规律。

To study the performance of high fly-ash content concrete（ HFCC）,the mix design model was used to complete into strength grade 42. 5 Portland cement concrete with different content such as 0%,10%,20%,30% and 40%by using the mass method. Through measuring,the variation law of air content in concrete mixture with the fly ash content and water-binder ratio was obtained.
