Recycled concrete replaced by brick-concrete recycled coarse and fine aggregate and preparation method thereof
The invention relates to recycled concrete replaced by brick-concrete recycled coarse and fine aggregate. The mass percent of the brick-concrete recycled fine aggregate in the fine aggregate is 10-25%; the brick-concrete recycled fine aggregate is obtained by compounding recycled red brick fine aggregate and recycled concrete fine aggregate, and the mass percent of the recycled red brick fine aggregate is 50-75%; the mass percent of the brick-concrete recycled coarse aggregate in the coarse aggregate is 10%-20%; the brick-mixed recycled coarse aggregate is obtained by compounding recycled red brick coarse aggregate and recycled concrete coarse aggregate, and the mass percent of the recycled red brick coarse aggregate is 50-75%. The brick-concrete recycled fine aggregate partially replaces natural fine aggregate in the concrete, the brick-concrete recycled coarse aggregate partially replaces natural coarse aggregate in the concrete, and the prepared recycled concrete has excellent cubic compressive strength and axial compressive strength and also has excellent elastic modulus, Poisson's ratio and frost resistance.
本发明涉及一种砖混再生粗细骨料替代的再生混凝土，所述细骨料中砖混再生细骨料的质量百分比为10％～25％；所述砖混再生细骨料为再生红砖细骨料和再生混凝土细骨料复配得到，再生红砖细骨料的质量百分比为50％～75％；所述粗骨料中砖混再生粗骨料的质量百分比为10％～20％；所述砖混再生粗骨料为再生红砖粗骨料和再生混凝土粗骨料复配得到，再生红砖粗骨料的质量百分比为50％～75％。本发明用砖混再生细骨料部分替代混凝土中的天然细骨料，砖混再生粗骨料部分替代混凝土中的天然粗骨料，制备得到的再生混凝土具有优异的立方体抗压强度和轴心抗压强度，同时具有优异的弹性模量、泊松比和抗冻性能。
