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：
