Plant ash recycled aggregate concrete and preparation method thereof
The invention discloses plant ash recycled aggregate concrete and a preparation method thereof, and relates to the technical field of building materials, the plant ash recycled aggregate concrete is prepared from the following raw material components: solid waste mixed gelling powder, CMA, cement, recycled aggregate, water, river sand and a water reducing agent according to a mass ratio of 1: (0.46-0.53): (6.12-13.58): (27.87-32.25): (5.77-7.01): (12.31-25.03): (0.05-0.12); the solid waste mixed gelling powder comprises plant ash and blast furnace slag; the mass ratio of the plant ash to the blast furnace slag is 1: 1. By adding the plant ash, the slag and the CMA, the durability of the concrete can be remarkably improved, the sensitivity to chemical erosion is reduced, the environmental load is reduced, the service life of the concrete is prolonged, and the requirements of the concrete on safety and durability of a building structure are met.
本发明公开了一种草木灰再生骨料混凝土及其制备方法，涉及建筑材料技术领域，其原料组分及其质量比如下：固废体混合胶凝粉料：CMA：水泥：再生骨料：水：河砂：减水剂=1：（0.46～0.53）：（6.12～13.58）：（27.87～32.25）：（5.77～7.01）：（12.31～25.03）：（0.05～0.12）；所述固废体混合胶凝粉料包括草木灰、高炉矿渣；所述草木灰和高炉矿渣的质量比为：1:1。通过加入草木灰、矿渣以及CMA，可以显著提高混凝土的耐久性，降低对化学侵蚀的敏感性，降低环境负荷，延长混凝土的使用寿命，满足其在建筑结构的安全以及耐久性能的要求。
