Abstract

Abstract

The tests for the limit moisture content and compaction on Malan loess from Sanmenxia in Henan mixed with different proportions of bentonite and HDTMA were conducted to explore the effect mechanism of bentonite and HDTMA on the workability of loess liners in landfills. The plasticity index of loess increased from silt to clay when the mass content of bentonite was more than 10%, and to mix HDTMA with a mass content less than 4% could optimize the physical properties of loess. Besides, both of the bentonite and HDTMA could buffer the negative effects of salts on physical properties of loess. The maximum dry density and optimal moisture content of the loess would respectively be increased and reduced with the increase of the bentonite content. The addition of HDTMA was benefit to reduce the maximum dry density of loess, but had a little influence on the optimal moisture content. In the microstructure, the HDTMA changed the structure of clay particles; the increase of bentonite made clay particles of being adhered to coarse particles occupy more spaces. Based on the data by tests,a linear function relation between the maximum dry density and the optimal moisture content for the modified loess was proposed. From the perspective of workability, the proportion of bentonite should be more than 10% and the proportion of HDTMA should be less than 2% in loess for liners of landfills.
