Evaluation of physico-mechanical properties of rock materials due to cyclic thermal treatments has significant implication towards safe and sustainable development of various underground rock engineering structures. Although Basaltic terrains, owing to its high hardness, low porosity and permeability, possess and often considered for potential sites for geothermal energy extraction, deep geological repository such as safe disposal of nuclear waste and various underground rock engineering constructions, the effect of temperature variations on engineering properties of basalt has not gained significant attention till date. The present study focuses on investigation of the effects of cyclic heating-LN2 (Liquid nitrogen) cooling treatments on the physico-mechanical properties of basalt. The prepared specimens were heated at different temperatures up to a targeted temperature of 600 °C and then immediately cooled in LN2. The same process is continued for one cycle and five cycles (i.e. one time and five times heating at a particular temperature followed to LN2 cooling). It has been found that the porosity values were increased ~ 146% and ~ 207% after first and fifth cycles, respectively, at 600 °C. The P-wave velocity (Vp) decreases ~ 19% and ~ 26%, and the S-wave velocity (Vs) decreases ~ 16% and ~ 26% after first and fifth cycles, respectively, at 600 °C. It is observed that Vs is quite efficient in inferring the thermal-induced microstructural changes at temperature 200 °C. Consequent to thermal-induced physical changes, the Brazilian strength of basalt was also decreased ~ 42% with reference to untreated specimens at 600 °C in case of N-C (fifth) specimens.
