Abstract: In order to study the hardening process of ultra-high strength concrete(UHSC) with cement-silica fume-slag-fly ash binder, orthogonal design was applied to the mix proportion of UHSC, and the hardening process of UHSC was studied. Test results showed that, with the increase of water-binder ratio, the flowabilities of UHSC increased significantly, compressive strengths at different ages decreased. With the increase of silica fume content, the flowabilities of UHSC decreased significantly, compressive strengths increased first and then decreased. With the increase of slag content, the flowabilities of UHSC had no obvious change, compressive strengths increased first and then decreased. With the increase of fly ash content, the flowabilities of UHSC increased first and then decreased, compressive strengths at early age decreased evidently, compressive strengths at later age increased first and then decreased.
