Shell-doped carbon sequestration ecological concrete and preparation method thereof
The invention belongs to the technical field of building materials, and relates to shell-doped carbon sequestration ecological concrete and a preparation method thereof.The concrete is prepared from natural coarse aggregate, artificially crushed shell coarse aggregate, natural fine aggregate, artificially crushed shell sand, cement, fly ash, a water reducing agent and water; the mass ratio of the natural coarse aggregate to the artificially crushed shell coarse aggregate is 1: (0.2-0.3), and the mass ratio of the natural fine aggregate to the artificially crushed shell sand is 1: (0.6-0.7). According to the invention, the shells are simultaneously used as coarse and fine aggregate substitutes to prepare the concrete, the optimal mixing proportion of the shell doping amount and the specific preparation method are disclosed, and the prepared concrete is greatly improved in strength and excellent in carbon sequestration performance, meets the requirements of engineering for concrete, and has relatively strong practical significance.
本发明属于建筑材料技术领域，涉及一种掺贝壳固碳生态混凝土及其制备方法，所述混凝土由以下成分组成：天然粗骨料、人工破碎贝壳粗骨料、天然细骨料、人工破碎贝壳砂、水泥、粉煤灰、减水剂以及水，且所述天然粗骨料与人工破碎贝壳粗骨料的质量比为1：0.2～0.3，天然细骨料与人工破碎贝壳砂的质量比为1：0.6～0.7。本发明同时将贝壳作为粗、细骨料替代品制成混凝土，公开了掺入贝壳量的最优配合比及具体的制备方法，所制备的混凝土强度提高较大，固碳性能优秀，满足工程所需混凝土需求，具有较强的实际意义。
