Study on the Effect of Curing Condition on the Performance of FBC Ash

摘要：

　　The cementitious system containing FBC ash is usually associated with volume expansion when cured in the normal temperature,due to its relatively high SO3 content.This paper presents a further study on the effect of different curing conditions on the flexural and compressive strength of FBC ash-Portland cement clinker mortar and linear expansion ratio of FBC ash-Portland cement clinker paste.The results show that autoclaved curing is more beneficial to increasing mortar strength in early days than standard curing,but with slow strength development in later period.Moreover,autoclaved curing could decrease the expansion of FBC ash greatly.This study confirms that the expansion of FBC ash can be significantly inhibited by autoclaved curing.
