Abstract

It is well known fact that all rocks exhibit brittle properties and time depends strain properties(creep). Ancks is believed to be essential in the field of Civil andtunnelling. The rock and concrete creep in various forms of loa ding conditions and physical environment are reviewed. Acomparison of creep behaviour between rocks and concrete is pro vided, in order to bring two existing relativelyindependent methods of predicting creep strain closer together. It was felt that the physical process in the creep of rockswould be similar to the process in creep of concrete. Since exp elastic(creep) mechanical behaviour of all crystalline solids ( i.e. concrete, rocks, ceramics and refractories) and singlematerials have a common base. Also a comparison of the results for the accepted methods of estimating creep in rocksthe knowledge of deformational characteristics of thesetwo materials.
