Abstract
Description
technical field
[0001] The invention belongs to the technical field of geotechnical engineering materials, and relates to a nano-fiber curing agent for disintegrating carbonaceous mudstone and its preparation and use methods. Background technique
[0002] Carbonaceous mudstone contains a large amount of clay minerals such as kaolinite, illite, and montmorillonite with strong hydrophilicity. Water sensitive, has the characteristics of water absorption expansion, loss of water shrinkage, and is prone to softening and disintegration, resulting in a significant decrease in various mechanical properties. Carbonaceous mudstone is widely distributed in hot and humid areas, and the rainfall in hot and humid areas is large, frequent rainstorms, and the seasonal variation of atmospheric temperature and humidity is large. The disintegration of carbonaceous mudstone is formed, and the disintegration of carbonaceous mudstone can easily cause secondary wetting deformation, continuous dis...
