| description | The invention relates to the technical field of concrete, and provides 200 MPa-grade steam-curing-free ultra-high performance concrete containing coarse aggregate and a preparation method of the 200 MPa-grade steam-curing-free ultra-high performance concrete. The ultra-high performance concrete is prepared from the following raw materials in parts by mass: 100 parts of cement, 15 to 20 parts of silica fume, 30 to 35 parts of fly ash, 95 to 105 parts of fine aggregate, 85 to 140 parts of coarse aggregate, 20 to 25 parts of water, 2 to 5 parts of water reducing agent and 19 to 33 parts of steel fiber. According to the ultra-high performance concrete provided by the invention, the components mainly comprise conventional materials and waste materials, and the raw materials are few in variety, easy to obtain and low in cost. According to the preparation method of the ultra-high performance concrete provided by the invention, the ultra-high performance concrete is subjected to forming maintenance by adopting a sola |
