Method for treating over-wet muck by using carbide slag
The invention provides a method for treating over-wet muck by using carbide slag, which comprises the following steps: calcining the carbide slag at 600-980 DEG C for 30-150 minutes to obtain dry powder with the water absorption rate of 20-32%; the method comprises the following steps: S1, mixing the dry powder obtained by calcining the carbide slag with the over-wet muck to obtain a mixture; s2, the mixture is placed aside, and when the water content of the mixture is reduced to the optimal water content, the road filling material is obtained. According to the method for treating the over-wet muck through the carbide slag for road filling, the same effect of treating the over-wet muck through quick lime can be achieved, but the production cost and the environmental load are lower.
本发明提供了一种利用电石渣处理过湿渣土的方法，先将电石渣在600‑980℃的温度下煅烧30‑150min，得到吸水率为20％‑32％的干燥粉末；然后将该干燥粉末用于处理过湿渣土，包括以下步骤：S1：将电石渣煅烧后得到的干燥粉末与过湿渣土混合后，得到混合物；S2：将所述混合物进行搁置，待所述混合物的含水率降低到最佳含水率时，即得到路用填筑材料。提供的一种利用电石渣处理过湿渣土用于道路填筑的方法可以达到生石灰处理过湿渣土同等的效果，但生产成本和环境负荷更低。
