Recycled aggregate negative carbon pervious concrete and preparation method thereof
The invention discloses recycled aggregate negative carbon pervious concrete and a preparation method thereof, and relates to the field of pervious concrete. The recycled aggregate negative carbon pervious concrete is prepared from the following components in parts by mass: 1186 to 1423 parts of recycled coarse aggregate, 54 to 68 parts of fine aggregate, 221 to 263 parts of cement, 147 to 175 parts of coal ash, 111 to 132 parts of water, 3.37 to 4.01 parts of a water reducing agent, 263 to 285 parts of special gel and 3.68 to 4.38 parts of bacterial powder. According to the recycled aggregate negative carbon pervious concrete, the surface of the recycled aggregate is wrapped with the specially-made gel, the bacterial powder with the biological enzyme catalysis function is introduced, the hardness of the recycled aggregate is improved, microcracks and pores are sealed, the mechanical property of the pervious concrete is effectively improved, the pervious concrete is endowed with the carbon absorption and fixation performance, and low-carbon environment-friendly production is achieved; the current environmental protection and dual-carbon concepts are met.
本发明公开一种再生骨料负碳透水混凝土及其制备方法，涉及透水混凝土领域。该再生骨料负碳透水混凝土，按质量计包括以下组份：再生粗骨料1186～1423份，细骨料54～68份，水泥221‑263份，粉煤灰147‑175份，水111‑132份，减水剂3.37～4.01份，特制凝胶263‑285份，菌粉3.68‑4.38份。该再生骨料负碳透水混凝土，通过将特制凝胶裹附于再生骨料表面并引入具有生物酶催化作用的菌粉，改善再生骨料硬度并封闭微裂缝和孔隙，不仅有效提高了透水混凝土力学性能，还赋予透水混凝土吸碳固碳性能，实现低碳环保生产，符合当前环境保护和双碳理念。
