Abstract

Strength and durability are crucial factors for the selection of rocks for building stones. This paper focuses on the study and evaluation of rocks of the Lesser Himalaya based on their physical properties, strength and durability. Nine different sites were selected for sampling appropriate rock types for building stones. Physical properties such as water absorption value, dry density, bulk specific gravity, saturation coefficient, porosity were determined. For mechanical strength, point load test and for chemical properties acid immersion test, salt crystallization test, methylene blue adsorption test and ethylene glycol soak test were carried out. Rocks of quartzite, granite, marble and dolomite showed higher strength values whereas rocks of quartzite, amphibolite and augen gneiss showed lower strength value. However, in terms of durability almost all rocks showed promising results except for carbonate rocks, i.e., marble and dolomite. Therefore, marble and dolomite are suitable for only interior uses such as wall cladding and interior flooring. Granite, metasandstone and quartzite with spaced foliation are suitable for dimension stones for both exterior and interior uses. Augen gneiss, amphibolite and quartzite with low strength and high durability are suitable for interior use only. From the evaluation, most of rocks showed suitable results regarding durability test.
