Abstract In this study, marble specimens were used to investigate the effects of freezing and thermal cyclic loading on physical mechanical properties. For purpose, four types considered, including freezing-cooling (F–C), heating–cooling (H-C), freezing-cooling-heating (F–C-H) heating–cooling-freezing (H-C-F). The changes observed in properties analyzed temperature extend shifting from − 30 °C 160 °C. To achieve goal, two blocks with a dimension × cm 3 selected. Then, compressive shear wave...
Concrete specimens used in this study as artificial rock samples were created to investigate the effects of grain size and specimen on mechanical properties cementitious material. For purpose, three concrete blocks produced which sizes 12, 20, 25 mm used. The cylindrical diameter 56, 68, 72, 94 prepared. Nine beams determine fracture toughness specimens. Results showed that enhancement uniaxial compressive strength with 72 was monotonic a result increased size, whereas it took but decreasing...
Rock engineering projects have always been constructed on different (from micro to macro) scales. This makes understanding rock behaviour at scales essential. In previous statistical studies igneous hard rocks, the correlation of uniaxial compressive strength (UCS) values in diameters with estimations specimen size effect models was weak. view this knowledge gap, present research proposed a model appropriate rocks. also aimed discussing and grain UCS concrete specimens. To achieve these...
The acoustic emission (AE) location technique and fault-plane solution method were used to evaluate the temporal-spatial evolution, released energy variation of micro-cracks, difference in b-values for different types micro-cracks during granite strain burst tests. Results show that AE locations coincide with macroscopic cracks ejection zone. are scattered fracture zone after unloading. fragment was results combined action shear, tensile, compressional micro-cracks; furthermore, from largest...
