The invention relates to the technical field of concrete materials, in particular to a high-strength concrete brick containing recycled aggregate, which comprises cement, gravel, slag powder, aggregate and a water reducing agent, the aggregate comprises recycled aggregate, carbon black and silicon carbide. The preparation method comprises the following steps: adding the cement, the gravel, the slag powder, the aggregate and the water reducing agent into a stirrer, stirring and mixing to form a mixture, adding water, stirring to form slurry, adding the slurry into a mold, carrying out compression molding, demolding, carrying out primary maintenance on the brick subjected to compression molding, and carrying out secondary maintenance. The problems that in the prior art, a concrete brick prepared from recycled aggregate is low in heat conductivity coefficient and low in strength are solved. The slag powder and the aggregate are added into the high-strength concrete brick, so that the performance of the concrete brick can be improved, and the prepared concrete brick body has the advantages of high strength, light self weight, strong construction adaptability, high thermal insulation performance and long service life.
本发明涉及混凝土类材料技术领域，特别是涉及一种含有再生骨料的高强度混凝土砖，包括：水泥、砂石、矿渣粉、骨料、减水剂；所述骨料包括：再生骨料、炭黑、碳化硅。制备方法为：将水泥、砂石、矿渣粉、骨料和减水剂加入搅拌机中搅拌混合形成混合料，再加入水搅拌形成浆料，将浆料加入模具中压制成型后脱模，将压制成型的砖块进行一次养护，再进行二次养护，即可。本发明解决现有技术中采用再生骨料制备的混凝土砖存在导热系数较低、强度较低的问题。上述高强度混凝土砖添加矿渣粉和骨料可以提高混凝土砖的性能，制备得到的混凝土砖体具有强度高、自重轻，施工适应性强、保温性能高以及使用寿命长的优点。
