粉煤灰的不同品质主要是指钙含量方面的差异性。同时,既往大量的研究资料中显示:高钙粉煤灰掺入下对于混凝土的力学性能、碳化性能、以及水化性能均有不同程度上的影响,为进一步展开对粉煤灰品质变化相对于混凝土性能影响程度的评估工作,本文采取试验研究的方式,入选高钙粉煤灰以及低钙粉煤灰两类不同品质的粉煤灰原料,研究不同粉煤灰掺入下对混凝土各方性能的影响情况,希望能够为相关工程中对混凝土的使用提供参考。 The different qualities of fly ash mainly refer to the differences in calcium content. At the same time, a large number of previous studies have shown that the mechanical properties, carbonization properties and hydration properties of concrete are affected to varying degrees with the incorporation of high-calcium fly ash. In order to further expand the quality of fly ash, Concrete performance impact assessment of the work, this paper to take the pilot study, selected high-calcium fly ash and low-calcium fly ash of two different qualities of fly ash raw materials to study the different fly ash mixed concrete performance The impact of the situation, hoping to provide reference for the use of concrete in related projects.
