Recycled concrete aggregate reinforced by using construction waste micro powder and preparation method of recycled concrete aggregate
The invention discloses a recycled concrete aggregate reinforced by using construction waste micro-powder, the recycled concrete aggregate is composed of a matrix, a modified wrapping layer and a surface reinforced layer, the matrix is a recycled aggregate, the modified wrapping layer is reinforced slurry, and the surface reinforced layer is carbide; wherein the recycled aggregate accounts for 80%-95% by mass, the reinforced slurry accounts for 4%-15% by mass, and the carbide accounts for 1%-5% by mass. The invention also provides a preparation method of the recycled concrete aggregate. According to the method, the raw materials are easy to obtain, the waste concrete aggregate and the micro powder thereof are utilized to the maximum extent, waste utilization and environmental protection are achieved, the cost is low, the technological process is simple, engineering practice application is facilitated, and the prepared modified recycled concrete aggregate is excellent in physical and mechanical property and wide in application prospect.
本发明公开了一种利用建筑垃圾微粉强化的再生混凝土骨料，所述再生混凝土骨料由基体、改性包裹层与表面强化层组成，所述基体为回收骨料，所述改性包裹层为强化浆液，所述表面强化层为碳化物；其中，质量份数为：所述回收骨料占80％‑95％，所述强化浆液占4％‑15％，所述碳化物占1％‑5％。本发明还提供了所述再生混凝土骨料的制备方法。本发明方法原料易得，最大程度地利用了废弃混凝土骨料及其微粉，利废环保、成本低、工艺流程简单，便于应用工程实际，制备的改性再生混凝土骨料物理力学性能优异，应用前景广阔。
