| Abstract | La stabilisation des sols mous a été pratiquée longtemps en mélangeant des ajouts, tels que le ciment, la chaux et les cendres volantes au sol pour augmenter sa résistance. Cependant, il y a un manque d’investigations sur l’utilisation de la pouzzolane naturelle seule ou combinée avec la chaux pour les applications d’amélioration des sols. Un programme expérimental a été entrepris pour étudier l’effet de la chaux, la pouzzolane naturelle ou leur combinaison sur les caractéristiques géotechniques des sols mous. La chaux ou la pouzzolane naturelle ont été ajoutées aux sols par des teneurs de 0-10% et 0-20% respectivement. Les échantillons préparés ont été soumis aux essais de compactage et de résistance à la compression non confinée. Les échantillons ont subis des périodes de cure de 1, 7, 28 et 90 jours après quoi ils ont été soumis aux essais de la résistance à la compression non confinée. Basé sur les résultats favorables obtenus, ilpeut être conclu que les sols mous argileux peuvent être stabilisés avec succès par l’action combinée de la chaux et de la pouzzolane naturelle. Puisque la pouzzolane naturelle est beaucoup moins chère que la chaux, l’addition de la pouzzolane naturelle dans le mélange chaux-sol peut en particulier devenir attirante et avoir comme conséquence une réduction des coûts de la construction. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
