Carbon sequestration concrete prepared from waste red bricks and preparation method of carbon sequestration concrete
The invention belongs to the technical field of building material modification, and particularly relates to carbon sequestration concrete prepared from waste red bricks and a preparation method of the carbon sequestration concrete. The recycled red brick is prepared from the following raw materials in parts by mass: 138 to 150 parts of infiltrated modified recycled red brick coarse aggregate, 92 to 100 parts of natural coarse aggregate, 118 to 134 parts of sand, 24 to 40 parts of recycled red brick fine sand, 53.5 to 60 parts of cement, 7.5 to 10 parts of fly ash, 11.5 to 15 parts of slag, 0.75 to 1.5 parts of activated carbon fiber, 38 to 42 parts of water and 4.6 to 8.3 parts of carbon sequestration enhancer. The waste red bricks are adopted as raw materials, resource waste is reduced, and cost is reduced; the porous structure of the waste red brick increases the contact area, so that more carbon dioxide molecules are favorably adsorbed and embedded, and the carbon sequestration effect is enhanced; in addition, the prepared concrete also has good freezing resistance and chemical erosion resistance, and can effectively resist external environment change and enhance durability.
本发明属于建筑材料改性技术领域，具体涉及利用废弃红砖制备的固碳混凝土及其制备方法。由以下质量份数的原料制成：浸润改性再生红砖粗骨料138‑150份、天然粗骨料92‑100份、砂子118‑134份、再生红砖细砂24‑40份、水泥53.5‑60份、粉煤灰7.5‑10份、矿渣11.5‑15份、活性炭纤维0.75‑1.5份、水38‑42份和固碳增强剂4.6‑8.3份。本发明采用废弃红砖作为原料，减少资源浪费，降低了成本；废弃红砖的多孔结构增加了接触面积，有利于吸附和嵌入更多二氧化碳分子，增强固碳效果；此外，所制备的混凝土还具备良好的抗冻性和耐化学侵蚀性能，可以有效抵御外部环境变化，增强耐久性。
