| Abstract | Atmospheric pollutants are changing due to policies aiming at attenuating climate change. Some of the results of these measures are the current inversion on the SO$_{2}$/NO$_{x}$ proportion and the pH increase of acid rains to 5 in some areas. The aim of this study was to have a better understanding of the relation between the microstructural and chemical characteristics of carbonated stones and their response to acid rain effects. This work also compared the response of natural stones as opposed to an artificial stone used in their replacement in the Orval Abbey (Belgium). Three natural and one reconstituted stones were selected. Nitric and sulphuric acidic solutions at pH = 5 were tested. For each solution, two tests of “passive immersion” and “active immersion” were conducted. Variations in weight, porosity, dissolved concentrations, colour and surface topography were measured. Stone SEM observations were additionally performed. The results indicate that active immersion is more effective than the passive one. The pore connectivity plays a key role in the stone dissolution and entails a difference between passive and active conditions. The different effect of nitric and sulphuric acids is related to the stone type. In spite of the initial presence of sulphur, the artificial stone appears less sensitive than the natural stone it replaces, due to its low pore connectivity and the concentrated distribution of iron oxides. |

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.
