| Abstract | This paper presents laboratory work to determine whether decreasing the strength of rock through water-saturating the specimens can reduce the amount of generated fines at failure. Three types of rocks were tested using the indirect tensile (Brazilian) test. The samples were randomly divided into two groups of gneiss, diorite and diabase (dolerite), one group of each rock type being tested in dry and the other in saturated conditions. The results indicated that the dry samples produced both higher tensile strength values and more fines than the saturated specimens. Cet article présente un travail de laboratoire visant à déterminer si la diminution de résistance d’une roche, obtenue par saturation, permet de réduire la quantité de poussières produites à la rupture. Trois types de roches ont été testés à l’aide de l’essai de traction indirecte (essai brésilien). Des échantillons de gneiss, diorite et diabase (dolérite) ont été partagés en deux groupes, ceux du premier groupe étant testés en conditions sèches, ceux du deuxième groupe en conditions saturées. Les résultats ont montré que les échantillons secs présentaient des valeurs de résistance à la traction plus importantes et produisaient plus de fines que les échantillons saturés. |

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.
