Ecological concrete for repairing river pollution and preparation method thereof
The invention discloses ecological concrete for repairing river pollution and a preparation method of the ecological concrete. The ecological concrete is prepared from the following components in parts by weight: 270 parts of river bottom mud, 120-230 parts of a gel material, 65-70 parts of water, 3-5 parts of a water reducing agent, 6-10 parts of a foaming agent and 2-4 parts of nano manganese dioxide. Based on a waste recycling concept, the river sediment is used for the ecological concrete, so that the mechanical property of the concrete can be guaranteed, the environmental harmfulness of the river sediment is reduced, the production cost is reduced, the nano-manganese dioxide has a good catalytic characteristic, the compressive strength of the ecological concrete can be improved, and the removal effect on heavy metals and organic matters can be improved; finally, the adsorption performance of the concrete-plant-microorganism system on pollutants is enhanced. The ecological concrete provided by the invention realizes resource sustainability, and has excellent environmental adaptability and enhanced river pollutant reduction performance.
本发明公开用于河流污染修复的生态混凝土及其制备方法，包括以下重量份的组分：河流底泥270份、凝胶材料120‑230、水65‑70份、减水剂3‑5份，发泡剂6‑10份，纳米二氧化锰2‑4份。本发明基于废物资源化概念，河流底泥用于生态混凝土即可保障混凝土的力学性能，减小了自身环境危害性，并降低了生产成本，纳米二氧化锰具有良好的催化特性，能提升生态混凝土的抗压强度，也能提高对重金属和有机物的去除效果，最终强化了混凝土‑植物‑微生物体系对污染物的吸附性能。本发明的生态混凝土实现了资源可持续化，具有优异的环境适应性及强化的河流污染物削减性能。
