Preparation method of regenerated waste concrete slurry and controllable low-strength material
The invention provides a preparation method of regenerated waste concrete slurry and a controllable low-strength material. The preparation method of the regenerated waste concrete slurry comprises the following steps: regulating and controlling the water content of waste concrete slurry, and carbonizing after the target water content is reached, so as to obtain the regenerated waste concrete slurry. According to the preparation method provided by the invention, the activity of the waste concrete slurry is improved by adopting a carbonization method, the water content of the slurry is controlled to be 80-300%, the operation is simple, and the cost is low. The prepared regenerated waste concrete slurry is applied to a controllable low-strength material and is compounded with regenerated sand powder and a small amount of additives for use, and the working performance of the controllable low-strength material can be met without adding water, cement and other cementing materials. In addition, the controllable low-strength material in the scheme can be effectively recycled, and carbon emission is reduced.
本发明提供一种再生废弃混凝土浆料的制备方法、可控低强度材料。再生废弃混凝土浆料的制备方法为：将废弃混凝土浆体进行含水率调控，达到目标含水率后进行碳化处理，得到再生废弃混凝土浆料。本发明提供的制备方法，采用碳化方法提升了废弃混凝土浆体的活性，并控制浆体含水率在80～300％之间，操作简单，成本低。将制备得到的再生废弃混凝土浆料应用到可控低强度材料中，与再生砂粉和少量外加剂复配使用，无需外加水和水泥等胶凝材料，便可以满足可控低强度材料的工作性能。此外，本方案的可控低强度材料可有效进行资源再利用，降低碳排放。
