The chemical and physical properties of typical loess, the granulometric composition, The variation of liquid and plastic limit, compaction characteristics, strength and its major influencing factors of improved-loess were studied in lab. Through experiments some results were obtained. The Results show that plasticity index of the improved-loess decreases after improvement, at the same time, its hydrophilicity weakened. As the variation of admixture kind, the optimum water content increases a bit, however, the maximum dry density decreases, and the changes of lime improved-loess is more obvious than cement, improved-loess. Other lime-improved loess or cementimproved loess, their strength increases with the curing time, at the increasing strength, the amplification of cohesion is superior to internal friction angle'. The chemical and physical properties of typical loess and its water-resistance were obviously improved through improving properties by chemical method, this would provide useful data and references for the usage of filling of subgrade in the railway passenger line and similar engineerings.","PeriodicalId":6400,"journal":{"name":"2011 Second International Conference on Mechanic Automation and Control Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75947768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment showed that the composition of films prepared by sputtering was affected by ambient condition and annealing temperature. The increasing Mg content was in favor of increasing crystal quality of films, and didn't change the wurtzite structure of films. The band gap changed between 3.4 and 4.0 eV, which was dependent on Mg content in films and consistent well with the previous reported theory on alloyed films. These results above showed that MgxZn1−xO films by sputtering could be used as barrier layers in ZnO-based heterostructures.","PeriodicalId":6400,"journal":{"name":"2011 Second International Conference on Mechanic Automation and Control Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75020615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results show: the electrical resistivity and unconfined compression strength are increased with the increase of age under every sodium hydroxide content; the electrical resistivity and unconfined compression strength are increased with the increase of sodium hydroxide content under every age; the unconfined compression strength of cemented soil has a linear correlation with the increase of electrical resistivity. The change of electrical resistivity is because of conductive pore structure and the number of ions.
