Effect of sulphate on the shear strength of lime-treated kaolinitic soil
Authors: Sivapullaiah P. V. , Sridharan A. , Ramesh H. N. 
Published: January 2006

Lime has been extensively used to improve the strength of fine-grained soils. It has recently been reported that the presence of sulphate in soils causes abnormal volume changes in lime stabilised soil. This paper presents the strength behaviour of lime-treated kaolinitic natural red earth in the presence of varying sulphate contents, up to 3%, after curing for periods of up to 365 days. Alteration of soil–lime reactions in the presence of sulphate leads to the formation of ettringite after curing for longer periods. The formation of these compounds affects strength development by cementation. However, after curing for short periods, the strength of lime-treated soil is improved in the presence of sulphate. It is only after curing for longer periods that the strength is decreased. Consequently the stress–strain behaviour and effective stress paths of treated soil cured for long periods show the behaviour of a normally consolidated soil rather than of cemented soils. The reduction in strength is due primarily to a reduction in the effective cohesion intercept. The effective friction angle has not been affected significantly. La chaux est largement utilisée pour améliorer la résistance des sols à grains fins. On a noté récemment que la présence de sulfate dans les sols cause des changements de volume anormaux dans les sols stabilisés à la chaux. Cet exposé montre le comportement de résistance d'une terre kaolinique naturelle traitée à la chaux en présence de diverses teneurs en sulfate, allant jusqu'à 3%, et après cuisson pendant des périodes allant jusqu'à 365 jours. Le changement de la réaction sol-chaux en présence de sulfate conduit à la formation d'ettringite après les périodes de cuisson les plus longues. La formation de ces composés affecte le développement de la résistance par cimentation. Cependant, après cuissons plus courtes, la résistance du sol traité à la chaux est améliorée par la présence de sulfate. Ce n'est qu'après la cuisson pendant des périodes plus longues que la résistance diminue. En conséquence, le comportement contrainte-déformation et les chemins de contrainte effective du sol traité et cuit pendant de longues périodes reflètent le comportement d'un sol consolidé de manière normale plutôt que celui de sols cimentés. La baisse de résistance est due principalement à une réduc-tion de l'interception de cohésion effective. L'ange de friction effectif n'est pas affecté de manière significative.
Lime treatment to control alkali induced heave in soils
Authors: Sivapullaiah P. V. , Manju  
Published: January 2006

The paper brings out the use of lime to control the high volume change induced by caustic soda solution in a non-swelling soil. Soil–alkali interactions, which produce mineralogical changes such as the formation of zeolite, can cause swelling in non-swelling kaolinite. The effect of the changes is reflected either in compression during the loading cycle or in swelling during rebound in one-dimensional consolidation tests, depending on the rate of formation of these minerals, which in turn depends on the concentration of alkali solution. Lime slurry solution can be used to control the induced volume changes by treating the contaminated soil by incorporating it in the soil that is likely to be contaminated and/or adding after contamination. The effectiveness of lime depends on the amount of lime, on the concentration of alkali, and on whether the lime is added before or after contamination. The higher the alkali contamination, the higher is the lime content required. The effectiveness of lime to control the volume change behaviour of alkali-contaminated soil is by inhibiting the formation of zeolite minerals and the formation of cementitious compounds. X-ray diffraction data support the proposed hypothesis. Cet exposé étudie l'utilisation de chaux pour contrôler les forts changements de volume causés par une solution de soude caustique dans un sol non gonflant. Les interactions sol-alcali, qui produisent des changements minéralogiques comme une formation de zéolite, peuvent causer un gonflement dans une kaolinite non gonflante. L'effet de ces changements est reflété soit par une compression pendant le cycle de chargement, soit par un gonflement pendant le rebond dans les essais de consolidation uni-dimensionnels, selon le taux de formation de ces minér-aux, taux qui lui-même dépend de la concentration de la solution alcaline. Une solution de boue de chaux peut être utilisée pour contrôler les changements de volume en l'incorporant dans le sol susceptible d'être contaminé et/ou en l'ajoutant après contamination. L'efficacité du traite-ment dépend de la quantité de chaux, de la concentration de l'alcali et du fait que la chaux a été ajoutée avant ou après contamination. Plus la contamination alcaline est élevée, plus la quantité de chaux sera importante. La chaux contrôle les changements de volume d'un sol contaminé aux alcalis en inhibant la formation de minéraux zéolites et la formation de composés cimenteux. Des données de diffraction aux rayons X soutiennent l'hypothèse proposée.
Periodic electroencephalogram complexes in a patient with variant Creutzfeldt–Jakob disease
Authors: Binelli Simona , Agazzi Pamela , Giaccone Giorgio , Will Robert G. , Bugiani Orso , Franceschetti Silvana , Tagliavini Fabrizio 
Published: January 2006

AbstractObjectiveBased on the current criteria, the diagnosis of “possible” or “probable” variant Creutzfeldt–Jakob disease (vCJD) implies the absence of periodic sharp wave complexes (PSWCs) in the electroencephalogram (EEG). To verify this point, we investigated the development of the EEG changes along the course of the disease in a pateint with vCJD.MethodsLong‐lasting EEG‐polygraphic recordings were performed once a month during the last year of illness.ResultsWe found the occurrence of a typical EEG periodic pattern in the late clinical stage of the vCJD patient.InterpretationIn the light of our finding, the diagnostic criteria for vCJD should be amended to include the possibility of a typical periodic EEG in advanced stages of disease in cases with long survival.
