The invention discloses recycled concrete and a preparation method thereof, and belongs to the field of concrete preparation. The recycled concrete comprises the following raw materials of: construction waste recycled coarse aggregate; cement; a mineral admixture; an excitant; soil; plant straw particles; waste rubber particles; an admixture; super absorbent resin beads; and water. The preparationmethod comprises the following steps of: step 1, uniformly mixing the first mineral admixture, the cement and the excitant, adding water accounting for 1/3-1/2 of the total weight, and performing uniform mixing to obtain a first intermediate product; 2, mixing the construction waste recycled coarse aggregate with the first intermediate product, and performing uniform stirring to obtain a second intermediate product; and 3, adding the plant straw, the waste rubber particles, the admixture, the super absorbent resin beads and the balance of water into the second intermediate product, and performing uniform mixing to obtain the recycled concrete. By adding the mineral admixture, the plant straw particles and the waste rubber particles into the components, an environment-friendly effect is achieved, and the prepared concrete is good in water permeability, proper in strength and suitable for vegetation growth.
本发明公开了一种再生混凝土及其制备方法，属于混凝土制备的领域，原料包括，建筑垃圾再生粗骨料、水泥、矿物掺合料、激发剂、土、植物秸秆颗粒、废弃橡胶颗粒、外加剂、超吸水树脂珠、水。制备方法包括以下步骤，步骤1：将第一矿物掺合料、水泥和激发剂混合均匀，加入总重量1/3‑1/2的水混合均匀，得第一中间产物；步骤2：将建筑垃圾再生粗骨料和第一中间产物混合，搅拌均匀得第二中间产物；步骤3：将植物秸秆、废弃橡胶颗粒、外加剂和超吸水树脂珠及余量的水加入第二中间产物中，混合均匀得再生混凝土。组分中通过加入矿物掺合料、植物秸秆颗粒和废弃橡胶颗粒，达到环保的效果，而且制备的混凝土透水性好，强度合适，适合植被生长。
