Preparation method for preparing functional concrete through carbon sequestration of wollastonite tailings
The invention discloses a preparation method for preparing functional concrete through carbon sequestration of wollastonite tailings. The functional concrete is prepared from the following raw materials in parts by weight: 80 to 90 parts of cement, 10 to 20 parts of wollastonite tailings, 140 to 160 parts of fine aggregate, 300 to 340 parts of coarse aggregate, 45 to 55 parts of water, 0.1 to 0.3 part of phosphorylated serine and 1 to 2 parts of polycarboxylate superplasticizer. The wollastonite tailings are selected as raw materials for preparation, high-valued utilization of the tailings is achieved, the use amount of cement is reduced, meanwhile, the silicon carbide limestone tailings can be well combined with a matrix when reacting in concrete, the fracture resistance, impact resistance and fireproof performance of the concrete are improved, and the service life of the concrete is prolonged. The concrete has the characteristics of good impact resistance, high breaking strength, good fireproof performance, energy conservation, environmental protection and the like.
本申请公开了一种硅灰石尾矿固碳制备功能混凝土的制备方法,包括如下重量份的原料:水泥80‑90份、硅灰石尾矿10‑20份、细骨料140‑160份、粗骨料300‑340份、水45‑55份、磷酸化的丝氨酸0.1‑0.3份、聚羧酸减水剂1‑2份。本发明选取硅灰石尾矿为原材料进行制备,实现了尾矿的高值化利用,减少了水泥用量,同时,通过碳化硅灰石尾矿的方式,使其在混凝土中反应时可以良好的与基体结合到一起,增加混凝土抗折、抗冲击及防火性能,使该混凝土同时具有抗冲击性好、抗折强度高、防火性能佳、节能环保等特点。
