This paper aims to investigate the effect of clay mineralogy on aggregate stability under the consideration of soil particle surface electric field in electrolyte solution.
Materials and methods
Aggregates of montmorillonite, kaolinite, and their compounds in different mass ratio were used as experimental materials. The degree to which the aggregates broke down under different electrolyte concentrations was evaluated both qualitatively and quantitatively.

This paper aims to investigate the effect of clay mineralogy on aggregate stability under the consideration of soil particle surface electric field in electrolyte solution.
Materials and methods
Aggregates of montmorillonite, kaolinite, and their compounds in different mass ratio were used as experimental materials. The degree to which the aggregates broke down under different electrolyte concentrations was evaluated both qualitatively and quantitatively. The aggregate breakdown process was observed with a video microscope. Furthermore, the percentage of particles (micro-aggregates and single particles) in diameter of <10, <5, and <2 μm to the total sample mass were measured based on Stokes equation.
Results and discussion
Different electrolyte concentrations correspond to different surface potential values around the particle surface. (1) The amount of released small particles for aggregate of clay compounds was several times higher than that for montmorillonite aggregate after breakdown. (2) Under high surface potential conditions, aggregate breakdown in a way of explosion was observed, and the critical surface potential values for the explosion increased with the increase of kaolinite content in aggregates. (3) The content of released particles for clay compound aggregates with high kaolinite content was much higher than that for aggregates with low kaolinite content under high surface potential values.
Conclusions
The coupling effects of electric field and clay mineralogy determined the aggregate stability of montmorillonite and clay compounds. This indicated that soil aggregates with relatively high silt content would be less stable than those with relatively high clay content under heavy rainfall; the most erosive soil might not be clay soils, but the silt soils, especially those under sudden storm after long-time drought.</description><identifier>ISSN: 1439-0108</identifier><identifier>EISSN: 1614-7480</identifier><identifier>DOI: 10.1007/s11368-015-1063-0</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Aggregates ; Clay ; Drought ; Earth and Environmental Science ; Electric fields ; Environment ; Environmental Physics ; Kaolinite ; Mineralogy ; Montmorillonite ; Sec 3 • Remediation and Management of Contaminated or Degraded Lands • Research Article ; Silt ; Soil aggregates ; Soil Science & Conservation ; Soils</subject><ispartof>Journal of soils and sediments, 2015-05, Vol.15 (5), p.1159-1168</ispartof><rights>Springer-Verlag Berlin Heidelberg 2015</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c415t-f575ed321202085160ea3031996bcfd5b2875ba118f389ad11f61d0125c40bc73</citedby><cites>FETCH-LOGICAL-c415t-f575ed321202085160ea3031996bcfd5b2875ba118f389ad11f61d0125c40bc73</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27924,27925</link.rule.ids></links><search><creatorcontrib>Xu, Chen-Yang</creatorcontrib><creatorcontrib>Yu, Zheng-Hong</creatorcontrib><creatorcontrib>Li, Hang</creatorcontrib><title>The coupling effects of electric field and clay mineralogy on clay aggregate stability</title><title>Journal of soils and sediments</title><addtitle>J Soils Sediments</addtitle><description>Purpose
