Lightweight ultra-high performance concrete
The invention relates to the technical field of concrete, and particularly discloses lightweight ultra-high performance concrete. The ultra-high performance concrete is prepared from the following components in parts by weight: 800 to 900 parts of cement, 200 to 280 parts of coarse aggregate, 1000 to 1300 parts of fine aggregate, 150 to 180 parts of silica fume, 400 to 480 parts of water and 12 to 20 parts of water reducing agent, the fine aggregate is composed of a fine aggregate I, a fine aggregate II and a fine aggregate III; the mesh number of the fine aggregate I is 20-30, the mesh number of the fine aggregate II is 50-80, and the mesh number of the fine aggregate III is 100-140. The raw materials are mixed according to the corresponding parts by weight to prepare the ultra-high performance concrete, the initial expansion degree of the obtained ultra-high performance concrete is 700-800 mm, and the 28d compressive strength is 150 MPa or above; the 28d tensile strength is 6 to 12MPa, and the 28d breaking strength is 12 to 25MPa.
本申请涉及混凝土技术领域，具体公开了一种轻质超高性能混凝土。所述超高性能混凝土包括水泥800‑900份，粗骨料200‑280份，细骨料1000‑1300份，硅灰150‑180份，水400‑480份，减水剂12‑20份；所述细骨料由细骨料Ⅰ、细骨料Ⅱ和细骨料Ⅲ组成；所述细骨料Ⅰ的目数为20‑30目，所述细骨料Ⅱ的目数为50‑80目，所述细骨料Ⅲ的目数为100‑140目。按照相应重量份数将上述原料进行混合，制得超高性能混凝土，所得超高性能混凝土的初始扩展度700‑800mm，28d抗压强度在150MPa以上；28d抗拉强度为6‑12MPa，28d抗折强度为12‑25MPa。
