摘要
通过正交试验的方法,对比研究了超细粉煤灰和粉煤灰对于混凝土强度的影响,结果显示和粉煤灰相比,超细粉煤灰优势明显,在合理掺量下,既可以满足混凝土的强度要求,又能有效提高工作性,节约水泥。
By means of orthogonal experiment, the contrast research of ultra-fine fly ash and fly ash for the influence of the strength of concrete is carried out. The results show that compared with fly ash, ultra-fine fly ash has the obvious advantages, under the reasonable dosage, it can satisfy the requirement of the concrete strength, and improve the workability, effectively save cement.
