Development and application of composite ultra - fine fly ash and special concrete technology 复合超细粉煤灰与特种混凝土技术的开发与应用
Study on the influence of compound ultra - fine fly ash on properties of recycled concrete 复合超细粉煤灰对再生混凝土性能影响的研究
The influence of steam curing regime on the strength of Ultra - Fine fly ash concrete 蒸养条件对超细粉煤灰混凝土强度的影响
Study on Reactive Powder Concrete with Ultra - pulverized Fly Ash 掺超细粉煤灰活性粉末混凝土的研究
In the date analysis, the ultra deviation analysis method and method deviation analysis method were applied. The paper analyzed the influence degree of the water glue ratio, fly ash mixed quantity and other factors to the strength of concrete 28d. 在数据分析中采用极差分析法和方差分析法,分析水胶比、粉煤灰掺量等四个因素对混凝土28d强度的影响程度。
