Biochar pervious concrete as well as preparation method and application thereof
The invention discloses biochar pervious concrete, which is prepared from the following raw material components in parts by weight: 55 to 70 parts of Portland cement, 35 to 50 parts of coarse aggregate, 0 to 6 parts of limestone, 5 to 12 parts of clay, 2 to 6 parts of fly ash, 8 to 15 parts of regenerated biochar powder, 3 to 4 parts of reinforcing agents, 2 to 5 parts of water reducing agents, 1.5 to 3.5 parts of air entraining agents and 100 to 120 parts of water, the preparation method of the biochar pervious concrete is characterized by comprising the following steps: 1) taking the raw materials in parts by weight, firstly putting the Portland cement, the coarse aggregate, the limestone, the clay and the fly ash into a stirrer for mixing, then adding half of water, and uniformly stirring by using the stirrer to obtain a concrete matrix; 2) adding the regenerated charcoal powder, the reinforcing agent, the water reducing agent, the air entraining agent and the residual water into the concrete matrix, and continuously stirring for 5 minutes to obtain a stirred mixture; and (3) pouring the stirred mixture into a mold, molding by adopting a vibration pressure composite molding method, and curing in a curing box after molding to obtain a finished product.
本发明公开了一种生物炭透水混凝土，其按重量份数计，包括以下原料组分：硅酸盐水泥55‑70份、粗骨料35‑50份、石灰石0‑6份、黏土5‑12份、粉煤灰2‑6份、再生生物炭粉末8‑15份、增强剂3‑4份、减水剂2‑5份、引气剂1.5‑3.5份、水100‑120份；所述生物炭透水混凝土的制备方法，其特征在于，包括以下步骤：1)按重量份取用各原料，首先将硅酸盐水泥、粗骨料、石灰石、黏土、粉煤灰放入搅拌机中混合后，加入一半的水，利用搅拌机搅拌均匀，得混凝土基体；2)向混凝土基体中，加入再生生物炭粉末、增强剂、减水剂、引气剂及剩余的水，继续搅拌5分钟，得搅拌混合物；3)将搅拌混合物倒入模具中，采用振动压力复合成型的方法进行成型，待成型后放入养护箱中进行养护，即得成品。
