Experimental study on durability of glass fiber reinforced cemented soil

Cemented soil is one of the main materials used in the pavement base of the construction of the airstrip, but it is vulnerable to water erosion in use. In order to solve the problem of poor water stability and durability of cemented soil, glass fiber was used to reinforce the cemented soil. In this paper, the dispersion tests of cemented soil reinforced by glass fiber with different soils, different fiber contents and lengths were carried out, and the dispersion resistances were studied. The results show that the Anti-dispersion performance of the specimens after immersion curing is obviously lower than that of the conventional curing specimens. The addition of fibers can narrow the gap between them and effectively improve the water stability of cemented soil. At the same time, the water stability of glass fiber reinforced cemented Xi’an soil is better than that of Sanya soil. In the range of study, when the fiber content is 0.3% and the length is 6 mm, the Anti-dispersion performance of cement soil is enhanced best. And when the fiber content is 0.3% and the length is 6 mm, the wear resistance of cemented soil is enhanced best. Generally speaking, when the length of glass fiber is 6 mm or 12 mm and the content is 0.3%, the reinforcement effect of cemented soil is the best. © 2021, Central South University Press.
