Method for preparing ceramic water permeable brick from tunnel waste slag
The invention discloses a method for preparing a ceramic water permeable brick from tunnel waste slag. The method comprises the following steps: crushing tunnel waste slag, mixing the crushed tunnel waste slag with fly ash and floating beads, adding silicon carbide, mixing in a mixing tank for 10-30min to prepare a mixed material, adding water, uniformly stirring in an electric stirrer, aging the mixed material for 12-36h, carrying out compression molding under the pressure of 5-25MPa to obtain a green body, drying, carrying out heat preservation on the green body in a high-temperature box-type resistance furnace at 1020-1080 DEG C for 20-80min, and cooling to room temperature to obtain a finished product. And discharging and cooling to room temperature. The compressive strength of the prepared water permeable brick is 18.5 MPa, the water permeation coefficient is 2.7 * 10 <-2 > cm/s, and reference is provided for resource utilization of the high-speed rail tunnel engineering waste slag.
本发明公开了一种利用隧道弃渣制备陶瓷透水砖的方法。首先将隧道弃渣破碎后与粉煤灰和漂珠混合，再加入碳化硅，在混料罐中混合10‑30min，制成混合物料，然后加入水，在电动搅拌器下拌匀，将混好的物料陈腐12‑36h，最后在5‑25MPa压力下压制成型得到生坯，烘干后，将生坯在高温箱式电阻炉中于1020‑1080℃下保温20‑80min，出炉降至室温，制成。本发明制备的透水砖抗压强度为18.5MPa，透水系数为2.7×10‑2cm/s，为高铁隧道工程弃渣的资源化利用提供参考。
