Title: Influence of fly ash /silica fume on the performance of low-grade concrete
Abstract: The effects on the low-grade concrete workability,strength and shrinkage of single fly ash,double-doped silica fume fly ash /silica fume were studied,the results show that fly ash and silica fume can improve the workability of fresh low-grade concrete and silica fume can increasing changes of concrete shrinkage in short term,resulting in early cracks,double-doped fly ash /silica fume can effectively improving the compressive strength of low-grade concrete in such a short term.
