Separation method of waste concrete aggregate and cement mortar
The invention belongs to the technical field of construction waste resource utilization, and discloses a separation method of waste concrete aggregate and cement mortar. Water with a certain filling degree is added into concrete, a temperature gradient heating method is adopted, cracks are generated in an interface transition area of aggregate and cement mortar of waste concrete gravels placed in a high-pressure kettle under the pressure at the temperature of 250-300 DEG C, and after mechanical stirring, the concrete is formed. And the separation rate of the aggregate of the waste concrete and the cement mortar reaches 90% or above. By the adoption of the technical scheme, efficient separation of aggregate and cement mortar of waste concrete can be achieved.
本发明属于建筑垃圾资源化利用技术领域，公开了一种废弃混凝土骨料和水泥砂浆的分离方法。通过在混凝土中加入一定填充度的水，采用温度梯度加热方法，在温度为250‑300℃条件下，使置于高压釜中的废弃混凝土碎石在压力下骨料和水泥砂浆的界面过渡区产生裂纹，且经机械搅拌后，实现废弃混凝土的骨料和水泥砂浆的分离率达到90％以上。采用本发明的技术方案，可以实现废弃混凝土的骨料和水泥砂浆的高效分离。
