Multi-scale fiber all-recycled aggregate geopolymer pervious concrete and preparation method thereof
The invention discloses multi-scale fiber fully-recycled aggregate geopolymer pervious concrete and a preparation method thereof. The multi-scale fiber fully-recycled aggregate geopolymer pervious concrete comprises recycled coarse aggregate, macroscopic fibers, microscopic fibers, nanoscale fibers, an alkali activator, slag and fly ash. The preparation method comprises the following steps: selecting regenerated broken stones, bricks and glass, screening, and preparing regenerated coarse aggregate according to target grading; adding nanoscale fibers into the alkali activator, and dispersing to obtain a nanoscale fiber suspension; carrying out dry mixing on the fly ash, the slag, the macroscopic fiber and the recycled aggregate, and fully mixing to obtain a mixture; respectively adding the prepared nanoscale fiber suspension and the microfibers into the obtained mixture, and stirring; and finally, after pouring forming, covering with a preservative film, curing at room temperature, demolding, and curing in a curing box to obtain the multi-scale fiber all-recycled aggregate geopolymer pervious concrete, thereby realizing high-valued utilization of the construction waste in road engineering.
本发明公开了一种多尺度纤维全再生骨料地聚物透水混凝土及其制备方法，多尺度纤维全再生骨料地聚物透水混凝土包括再生粗骨料、宏观纤维、微观纤维、纳米级纤维、碱激发剂、矿渣和粉煤灰。制备时，选用再生碎石、砖、玻璃，经筛分后根据目标级配配制再生粗骨料；将纳米级纤维加入到碱激发剂中并分散，制得纳米级纤维悬浮液；将粉煤灰、矿渣、宏观纤维和再生骨料干拌，使其充分混合得混合料；将制备好的纳米级纤维悬浮液继和微观纤维分别加入所得混合料中并搅拌；最后，浇筑成型后覆盖保鲜膜室温养护后脱模，并将其放入养护箱中养护，得到多尺度纤维全再生骨料地聚物透水混凝土，实现建筑垃圾在道路工程中的高值化利用。
