Method for preparing regenerated cementing material by using waste concrete
The invention discloses a method for preparing a regenerated cementing material by using waste concrete, and the specific preparation method comprises the following steps: S1, selecting a mixed raw material; s2, grinding the raw materials: fully crushing the raw stone material, putting the crushed raw stone material into a ball mill, carrying out wet grinding for 3-4 hours, discharging, and pouring the powder into a composite solution to carry out acid pickling treatment after the powder is ground into powder; s3, heating, melting and fully stirring the raw materials, and keeping the calcination temperature at 1050-1150 DEG C to obtain a molten mixed raw material; s4, performing annealing treatment and tempering treatment on the mixed raw materials, wherein the heat treatment temperature ranges from 240 DEG C to 320 DEG C; s5, cooling treatment: carrying out liquid nitrogen cooling rapid treatment on the raw materials; and S6, feeding the raw materials into a mixer, and carrying out homogenization treatment to obtain the gel raw materials. The waste concrete can be efficiently utilized to manufacture the gel material, more other broken stones and composite solutions are added into the raw materials, the raw materials can be subjected to acid pickling, more impurities are removed, the purity of gel is improved, and the method is more environment-friendly.
本发明公开了一种利用废弃混凝土制备再生胶凝材料的方法，具体制作方法包括以下步骤，S1，选取混合原料；S2，对原料磨料：先对原石材料进行充分的破碎，破碎后放入球磨机湿磨3‑4h后出料，在研磨成粉状后倒入复合溶液进行酸洗处理；S3、将原料进行加热熔化并充分搅拌，保持煅烧温度为1050‑1150℃，得到熔融混合原料；S4、对混合的原料进行退火处理，并进行回热处理，热处理温度为240‑320℃；S5、冷却处理：对原料进行液氮冷却快速处理；S6、再将原料送入混料机进行均化处理，即得到凝胶原料。本发明可高效的利用废弃混凝土进行制作凝胶材料，在原料中附加其他较多的碎石和复合溶液，可对原料进行酸洗，清除较多的杂质，提高凝胶的纯度，较为环保。
