A　systematic　experimental　study　on　the　compressive　strength　in　different　curing　system,　shrinkage,　and　penetration　resistance　of　ultra-high　performance　concrete　(UHPC)　mixed　with　coarse　aggregate　in　different　ratios　is　conducted.　The　experimental　research　can　draw　the　following　conclusions:　The　amount　of　gravel　has　no　discernable　effect　on　the　early-age　compressive　strength　of　UHPC　in　the　90　degrees　water　curing　and　autoclaved　curing;　while　as　the　amount　of　gravel　increases　in　lower　temperature　hot　water　or　standard　curing,　the　strength　of　specimens　decreases　firstly　and　increases　later,　while　the　shrinkage　gets　the　tendency　to　the　contrary;　when　the　gravel　content　(G/C)　takes　0.8,　there　is　a　largest　reduction　in　its　strength,　drying　shrinkage　and　the　self-shrinkage;　all　experimental　group　have　excellent　impermeability,　it　is　not　easy　for　moisture　to　penetrate　into　the　specimen　in　the　method　of　ordinary　concrete　seepage　test.
