Abstract
AbstractMany erosive environments, such as acidic or various salts, can cause damage to structures like roads, tunnels, and buildings. Various tests were conducted to investigate how the strength of cemented soil is affected by different soaking periods, types of saline solutions, and fibers. Samples including and excluding basalt fibers were tested in water, acid, and salt solutions for 1, 8, 19, 39, and 54 days. The results show that the strength of cemented soil soaked in clear water gradually increases with the increase of maintenance days, which is the development law of strength of cemented soil. As the soaking time increases, the unconfined compressive strength of soil samples soaked in acidic and salt environments gradually decreases. The addition of fiber to cemented soil slightly increases its strength compared to soil without fiber in the same solution concentration. This suggests that fiber has a distinct role in protecting cemented soil from erosion caused by erosive solutions.
