Abstract：Titanium slags are used instead of quartz sand to prepare UHPC.The influence of titanium slag gradation,UHPC sand cement ratio,and curing method on the compressive strength of UHPC was studied and its mechanism was analyzed by micro-scopic test.The results showed that the grading of titanium slag,the sand cement ratio,and the curing method all have a significant impact on the strength of titanium slag based UHPC.When the grading is medium∶small∶large=1∶0.6∶0.96,the sand cement ratio is 1.3,and it is standard cured for 2 days and then steamed at 90℃for 5 days,the strength of titanium slag based UHPC is the high-est,reaching 186.7 MPa.In addition,the strength of titanium slag UHPC can achieve most of the growth during steam curing for 3 days.The porous structure of titanium slag sand can better adsorb the surrounding slurry,increase the contact area between the two,thereby increasing the friction and making it tightly bonded,so that the compressive strength of UHPC is improved.
