Ultrasonic tomography to evaluate heat induced limestone decay and consolidation. Portuguese limestone heated at 600 °C and consolidated with ethyl silicate or nanolime. Petrophysic and elastic parameters were considered. Strong effect of fire decay and consolidation on physical and mechanical properties. Seismic tomography allowed visualization of consolidants impregnation capability.
