| 中文摘要: |
| 市政工程建设产生大量废弃淤泥，废弃淤泥处置成为难题，目前常采用固化方法进行处理。为使流动固化处理后淤泥流动性和强度达到泵送施工的要求，需要分析淤泥流动性的大小与含水率和固化材料掺量之间的关系。通过对固化淤泥流动性的试验，得出如下结论:固化淤泥流动度随淤泥含水率增加而增加，随水泥掺量增加而降低；相比坍落度法，流动度法操作简易，数据更具连续性。 |
| 英文摘要: |
| A large amount of waste sludge is produced in municipal engineering construction, and the disposal of waste sludge becomes a problem. At present, solidification method is often used for treatment. In order to make the fluidity and strength of the sludge reach the requirements of pumping construction, it is necessary to analyze the relationship between the fluidity of the sludge and the water content and the content of solidified materials. Through the test of the fluidity of solidified sludge, the following conclusions are drawn that the fluidity of solidified sludge increases with the increase of sludge moisture content and decreases with the increase of cement content. Compared with slump method, the fluidity method is easier to operate and more continuous in data. |
