Mineralogical Study on the Consistency Property of Bentonite Mixed Soil

Bentonite mixed soil, which is a mixture of bentonite with sand and gravel, can be easily compacted by adjusting the blending degree, it difficult for water to pass through exhibits low permeability. It widely used at construction sites because on-site has good workability. Examples its use include impermeable layers waste disposal measures contain heavy metals from rocks generated sites. The main component smectite, swelling clay mineral, property consistency characteristics determine engineering properties. In particular, permeability considered strongly influenced electrochemical properties crystal level peculiar smectite. this study, mechanism expression soil was investigated focusing on mineralogy Specifically, X-ray near-infrared analysis were performed clarify structure smectite adsorptivity molecules. change in interlayer distance clarified XRD. Information behavior molecules obtained NIR. From these analyses, we information swelling, micro-physical bentonite, related
