Experimental study and mechanisms of swelling properties of Xiashu-bentonite mixture

Xiasu-bentonite mixture is an alternative liner material,which plays an important role in the security of urban landfills.In this study,the swelling properties of 9 mixture samples with different initial water content(10% to 20%) and bentonite content(5% to 15%) were tested under different temperatures(30℃ to 50℃).The results indicate that the initial water content is a significant factor influencing the mixture’s natural properties.The swelling capacity decreases with increasing water content,a...
