Iron tailing ceramsite low-carbon concrete prefabricated stair and preparation method thereof
The invention relates to the technical field of constructional engineering, and particularly discloses an iron tailing ceramsite low-carbon concrete prefabricated stair and a preparation method thereof. An iron tailing ceramsite low-carbon concrete prefabricated stair comprises a concrete member and reinforcing bars embedded in the concrete member, and the concrete member comprises cement, fly ash, iron tailing-hydrotalcite composite powder, iron tailing ceramsite, quartz sand, graphene oxide, micro-nano CO2 bubble water, microorganisms, a water reducing agent and water; and the reinforcing bars are CRB600H reinforcing bars. The fly ash and the iron tailing-hydrotalcite composite powder are doped into the concrete used for prefabricating the stairs, so that on the premise of ensuring the strength of the concrete, the use amount of cement can be reduced as much as possible, the pollution of iron tailings to the environment is reduced, and the green and low-carbon development requirements of fabricated buildings are met.
本申请涉及建筑工程技术领域，具体公开了一种铁尾矿陶粒低碳混凝土预制楼梯及其制备方法。一种铁尾矿陶粒低碳混凝土预制楼梯，包括混凝土构件和埋设于混凝土构件内的配筋，所述混凝土构件包括原料：水泥、粉煤灰、铁尾矿‑水滑石复合粉料、铁尾矿陶粒、石英砂、氧化石墨烯、微纳米CO2气泡水、微生物、减水剂和水；所述配筋为CRB600H钢筋。本申请预制楼梯所用的混凝土中，掺加粉煤灰和铁尾矿‑水滑石复合粉料能够在保证混凝土强度的前提下，能够尽可能减少水泥的用量，减少铁尾矿对环境的污染，助力装配式建筑实现绿色低碳的发展要求。
