Machine-made sand recycled concrete of composite floor slab component and preparation method of machine-made sand recycled concrete
The invention discloses machine-made sand recycled concrete of a composite floor slab component and a preparation method of the machine-made sand recycled concrete. The compressive strength of the prepared recycled concrete in 28 days is larger than or equal to 33 MPa. The prepared machine-made sand and the recycled coarse aggregate have good economic value and ecological value, the preparation method provided by the invention is simple and easy to implement, convenient to operate and control and high in preparation efficiency and finished product percent of pass, and the prepared machine-made sand can replace second-class sand for use and has good mechanical strength and slump performance.
本发明公开了一种叠合楼板构件的机制砂再生混凝土及其制备方法，制得的再生混凝土28天的抗压强度≥33MPa。本发明制得的机制砂与再生粗骨料两种绿色材料具有良好的经济价值和生态价值，本发明提供的制备方法简单易行，操作控制方便，制备效率和成品合格率高，制得的机制砂能够代替二类砂进行使用，有着良好的机械强度和坍落度性能。
