淤泥固化技术有其特殊性

淤泥固化技术有其特殊性：1、一般水泥淤泥固化以后的强度不高、变形较大、容易开裂，在公路工程上的应用受到一定的限制。2、河道淤泥多为含腐殖酸软土，软土中的腐殖酸通过阻碍水化反应，分解水化产物等，严重影响水泥、石灰等材料的固化效果。在河道道路铺设的过程中带来困难，淤泥固化的速度缓慢会降低建筑工程的速度。
Sludge solidification technology has its particularity: 1. Generally, the strength of cement sludge after solidification is not high, the deformation is large, and it is easy to crack, so its application in highway engineering is limited to a certain extent. 2. 2. The river silt is mostly soft soil containing humic acid. The humic acid in the soft soil seriously affects the curing effect of cement, lime and other materials by hindering the hydration reaction and decomposing the hydration products. It brings difficulties in the process of river road laying, and the slow solidification speed of sludge will reduce the speed of construction engineering.
我国每年淤泥的产量很高，二次利用率很低，这样对环境会造成影响，同时也造成了资源浪费。但是淤泥其实是可以作为道路路基建设的基础材料，因为现有技术中的淤泥固化技术大多是直接添加水泥固化，固化以后的整体结构强度低，淤泥固化以后很难被应用到道路路基建设中。
The annual output of sludge in China is very high and the secondary utilization rate is very low, which will not only affect the environment, but also cause a waste of resources. However, sludge can actually be used as the basic material for road subgrade construction, because most of the sludge solidification technologies in the existing technology are directly added with cement for solidification. After solidification, the overall structural strength is low, and it is difficult to be applied to road subgrade construction after sludge solidification.
