Method for preparing carbonized reinforced recycled aggregate concrete
According to the method for preparing the carbonation-reinforced recycled aggregate concrete, raw materials for preparing the recycled aggregate concrete are dry materials and water, the dry materials comprise active magnesium oxide cement and carbonation-reinforced recycled concrete aggregate, and the mass ratio of the active magnesium oxide cement to the carbonation-reinforced recycled concrete aggregate is (1-3): (2-4); the water cement ratio is 0.55 to 0.65; the method for preparing the recycled aggregate concrete comprises the following steps: S1, stirring and mixing active magnesium oxide cement serving as a cement adhesive and carbonized reinforced recycled concrete aggregate serving as coarse aggregate, and adding water in the stirring process to obtain a fresh concrete mixture; s2, pouring and compacting are conducted, specifically, a fresh concrete mixture is poured into the model and compacted, and a concrete mixture is obtained; s3, trowelling is conducted; and S4, demolding and curing.
一种制备碳化强化再生骨料混凝土的方法，制备再生骨料混凝土所用原料为干料和水，干料包括活性氧化镁水泥和碳化强化再生混凝土骨料，活性氧化镁水泥与碳化强化再生混凝土骨料的质量比为1－3：2－4；水灰比为0.55－0.65；制备再生骨料混凝土的方法包括如下步骤：S1：利用活性氧化镁水泥作为水泥粘合剂，用碳化强化再生混凝土骨料作为粗骨料，将2种原料进行搅拌混合，在搅拌过程中加水，得新拌混凝土混合料；S2：浇筑压实：然后将新拌混凝土混合料浇筑到模型中，压实，得混凝土混合料；S3：抹平；S4：脱模固化。
