Resource utilization method of high-water-content sludge engineering muck
The invention provides a resource utilization method of high-water-content sludge engineering muck, which comprises the following steps: S1, adding a curing agent into the high-water-content sludge engineering muck for mixing, then performing dehydration treatment, and then performing crushing and screening to obtain semi-finished muck; s2, the semi-finished product muck is put into a carbonization chamber for carbonization curing, and a carbonized soil mixture is obtained; s3, mixing the carbonized soil with cement, an admixture, aggregate and sodium bicarbonate to obtain a carbonized and solidified soil mixture; and S4, crushing, screening, paving and rolling the carbonized and solidified soil mixture to obtain the base material. The high-performance pavement material obtained by adopting the method disclosed by the invention is high in strength, high in water stability coefficient and good in frost resistance.
本发明提供了一种高含水淤泥质工程渣土的资源化利用方法，包括以下步骤：S1、将高含水淤泥质工程渣土加入固化剂进行混合，然后脱水处理，再进行破碎筛分后得到半成品渣土；S2、将半成品渣土放入碳化室内进行碳化养护，得到碳化土混料；S3、将碳化土与水泥、掺合料、骨料和碳酸氢钠混合，得到碳化固化土混合料；S4、将碳化固化土混料进行破碎筛分，摊铺碾压，得到基层材料。采用本发明方法得到的高性能路用材料，其强度高，水稳系数高，抗冻性能好。
