Method for treating over-wet muck by using industrial waste gypsum
The invention provides a method for treating over-wet muck by using industrial waste gypsum, which comprises the following steps: uniformly mixing water-absorbing dry powder accounting for 5-30% of the mass of dry soil of the over-wet muck with the over-wet muck to form a mixture, then standing the mixture for 1-48 hours, and obtaining a road filling material prepared by using the industrial waste gypsum and the over-wet muck when the mixture reaches the optimal water content, the water-absorbing dry powder is prepared by calcining the industrial waste gypsum at the temperature of 100-500 DEG C for 30-90 minutes, so as to obtain the water-absorbing gypsum dry powder with the water absorption rate of 17-26.5%. According to the resource utilization method of the industrial waste gypsum provided by the invention, the over-wet muck treated by the industrial waste gypsum can be used as a filling material applied to a roadbed and a base layer of a road, and the commercial value and the popularization value are relatively high.
本发明提供了一种利用工业废石膏处理过湿渣土的方法，包括：将占过湿渣土干土质量5‑30％吸水干粉与过湿渣土混合均匀形成混合料，然后将混合料搁置1‑48h，待其达到最佳含水率时，即得到利用工业废石膏和过湿渣土制成的路用填筑材料；所述吸水干粉包括将工业废石膏在100℃‑500℃的温度的温度下煅烧30‑90min，得到吸水率为17‑26.5％的吸水石膏干粉。本发明提供了一种工业废石膏资源化利用的方法，通过本发明的方法，用工业废石膏处理的过湿渣土，能够作为应用于道路路基和基层的填筑材料，具有较高的商业化价值与推广价值。
