不同浇筑时间的粉煤灰自密实混凝土强度分析

Strength analysis of self-compacting concrete with fly ash at different pouring times

通过考虑粉煤灰自密实混凝土各不同组成材料的掺量对试验结果的影响,采用了五因素、四水平的正交设计方案研究不同时间成型的自密实混凝土强度与含气量的变化,试验研究证明不同时间成型的自密实混凝土的含气量不同,强度也会随之变化。

By considering the influence of fly ash self-compacting concrete composed of materials of different content on the test results, orthogonal design of five factors, four levels is adopted to investigate different time forming self-compacting concrete changes in the strength and air content. Experimental research shows that different time forming a self-compacting concrete have different air content and compressive strength as well as change.
