Recycled Concretes(再生混凝土)研究综述
Recycled Concretes 再生混凝土 - The main hurdle to MRA valorisation is its non-uniformity and certain intrinsic properties that have a direct effect on the performance of recycled concretes. [1] In order to study the influence of the characteristics of crushed bricks on recycled concrete, the author took the water-cement ratio (W/C) as the design goal, and crushed bricks as coarse aggregates to prepare five groups of recycled concretes with different W/C. [2] The recycled concretes were produced by replacing the Natural Coarse Aggregate (NCA) of the reference concretes with RCA in percentages of 50% and 100% by volume. [3]MRA 增值的主要障碍是其不均匀性和某些对再生混凝土性能有直接影响的内在特性。 [1] 为研究碎砖特性对再生混凝土的影响,作者以水灰比(W/C)为设计目标,以碎砖为粗骨料制备了5组不同W的再生混凝土。 /C。 [2] 再生混凝土是通过用体积百分比为 50% 和 100% 的 RCA 代替参考混凝土的天然粗骨料 (NCA) 来生产的。 [3]
