Abstract

Abstract: The sulfur amount of fly ash has a substantial influence on the intensity and stability of road base course. Elicited from an engineering case, this paper discusses and analyzes the mechanism of road base course expansion cracks,intensity decrease, and final destruction caused by high sulfur content fly ash, which is testified by indoor and outdoor experimentations. And it is also given as a reference of others professionals

Key words: fly ash, SO3, road base course, expansion, crack

摘要： 粉煤灰含硫量对路面基层的强度和稳定性有重要影响。本文从工程实例出发，分析探讨了高含硫量粉煤灰导致路面基层膨胀开裂、强度降低进而产生破坏的机理，并结合室内外实验予以验证。以期引起同行的注意与借鉴。
