Green low-carbon recycled concrete material as well as preparation method and application thereof
The invention belongs to the technical field of building materials, and particularly relates to a green low-carbon recycled concrete material and a preparation method and application thereof. The green low-carbon recycled concrete material provided by the invention is prepared from the following components: slag, fly ash, sodium silicate, tetrasodium 3-hydroxy-2, 2 '-iminodisuccinate, river sand, stones, modified biochar, modified montmorillonite, water and the like. Cement with high CO2 emission factors is replaced with industrial solid wastes with volcanic ash activity, such as slag with low CO2 emission factors, fly ash and the like, so that carbon emission of the concrete material is remarkably reduced, and meanwhile, the mechanical property of the concrete material can be improved by doping components such as modified charcoal and montmorillonite; carbon emission can be further reduced by sealing carbon with biochar, so that the technical problem of lack of high-performance green low-carbon recycled concrete in the prior art is solved.
本申请属于建材技术领域，尤其涉及一种绿色低碳再生混凝土材料及其制备方法和应用；本申请提供的绿色低碳再生混凝土材料，包括矿渣、粉煤灰、硅酸钠、3‑羟基‑2,2′‑亚氨基二琥珀酸四钠、河砂、石子、改性生物炭、改性蒙脱石以及水等成分；其中使用低CO2排放因子的矿渣、粉煤灰等具有火山灰活性的工业固废替代高CO2排放因子的水泥显著降低了混凝土材料的碳排放，同时掺杂改性生物炭和蒙脱石等成分可以提高混凝土材料的力学性能，并且通过生物炭封存碳可以进一步降低碳排放，从而解决现有技术中缺乏高性能的绿色低碳再生混凝土的技术问题。
