The Indian Himalayan Region (IHR) is one of the rich biodiversity regions of the world with over 10,000 plants, 300 mammals, 977 birds, 281 herpetofauna, 269 fishes, several species of invertebrates and microorganisms, many of which have global conservation significance. Despite significant ecological, hydrological and biological values, the fragile mountain ecosystems in the IHR are seriously threatened due to increasing anthropogenic pressures, mainly development. In the IHR, wildlife species are threatened due to poaching for meat, illegal wildlife trade, negative human–wildlife interactions (conflicts), habitat loss, habitat fragmentation and degradation due to developmental activities and natural resource use by humans. These have led to a decline in wildlife population, reduction in distribution range and in some cases local extinction of species.Full Text

The present study attempts to obtain the critical strains in concrete induced on account of reinforcement corrosion by simulating the expansive pressure of corrosion products using grout. Surface strains induced in hollow concrete cylinders due to expansion of grout filled inside the hollow portion were continuously monitored to experimentally validate the well-known thick-walled uniform cylinder model used in reinforcement corrosion problems. The study shows that expansive grout could effectively simulate the internal pressure generated in accelerated corrosion tests, and can be used as a means of obtaining critical strains in relatively shorter duration in laboratory studies.Keywords
