Cement concrete curb containing brick-concrete construction waste recycled aggregate and preparation method thereof
The invention relates to the technical field of building materials, in particular to a cement concrete curb containing brick-concrete construction waste recycled aggregate and a preparation method thereof. The cement concrete curb is prepared from the following raw materials in parts by weight: 13.5-16.5 parts of cement, 5-21 parts of brick-concrete recycled coarse aggregate, 2-7 parts of brick-concrete recycled fine aggregate, 3-5 parts of fly ash, 13-21 parts of sand, 29-50 parts of gravel, 0.02-0.03 part of concrete compacting agent, 0.4-0.7 part of early strength antifreezing agent, 0.8-1.6 parts of concrete preservative and 4.5-7 parts of water, wherein the mass ratio of bricks in the brick-mixed recycled coarse aggregate is less than or equal to 35%, and the mass ratio of bricks in the brick-mixed recycled fine aggregate is less than or equal to 35%. The cement concrete curb has good anti-corrosion performance, resource utilization of the brick-concrete construction waste is achieved, and pollution of the brick-concrete construction waste to the environment is effectively reduced.
本发明涉及建筑材料技术领域，具体涉及一种含砖混建筑垃圾再生骨料的水泥混凝土路缘石及其制备方法，包括以下重量份的原料组分：水泥13.5～16.5份，砖混再生粗骨料5～21份，砖混再生细骨料2～7份，粉煤灰3～5份，砂13～21份，碎石29～50份，混凝土密实剂0.02～0.03份，早强防冻剂0.4～0.7份，混凝土防腐剂0.8～1.6份，水4.5～7份，其中，所述砖混再生粗骨料中砖的质量占比≤35％，所述砖混再生细骨料中砖的质量占比≤35％。本发明具有良好的抗腐蚀性能，实现了砖混建筑垃圾的资源化利用，有效地降低了砖混建筑垃圾对环境的污染。
