摘要
可控低强度材料(CLSM)使用大量的建筑和拆除废物,与传统的回填材料相比,这种材料更具可持续性,并且可以降低成本。研究了再生细骨料(RFA)和再生微粉(RP)对CLSM力学和流变性能的影响。还考虑了水粉比和砂灰比的影响,以进行CLSM的混合比例的设计。
Controlled Low Strength Material(CLSM)can use large amount of construction and demolished waste,which is more sustainable and can reduce the cost compared with the traditional backfill material.The effect of recycled fine aggregate(RFA)and recycled powder(RP)on the mechanical and rheological properties of CLSM was studied.The effect of water-binder ratio and sand-binder ratio has also been considered to design the mixture proportioning of CLSM.
