Abstract:
Compared with silica fume, zeolite powder is a local mineral admixture with the low price. Zeolite powder was
used to replace silica fume to prepare ultra-high performance concrete （ UHPC). The effects of zeolite powder content,
water to binder ratio and volume content of steel fiber on the mechanical properties of UHPC were studied. The results show
that when part silica fume is replaced by zeolite powder, the 3 d strength are reduced. And with the increase of ages,
zeolite powder with the replacement rate of 15% （mass fraction) increases the strength of UHPC, while zeolite powder with
the replacement rate of 30% （ mass fraction) has l
