The Geotechnical Laboratory consist of a teaching lab and three research labs. These laboratories encompass approximately 1000 sqft. of the available laboratory space with all major regular laboratory functioning facilities such as microbalances, sieves stacks, and sieve shaker, oven, and etc. Additional important and relevant instrument include:
Ultrasonic Probe Transducer: Two 20 kHz probe system with a power rating of 450 (VerSonic 450) Watt and 1500 Watt (Sonics VC1500).
Power Amplifier: Two power generator working in a frequency range of 20 kHz to 1 MHz and 20 kHz to 500 kHz with a power rating of 2000 Watt (E&I 1240 L) and 500 Watt (ENI 1040L) respectively for supplying power to plate transducer.
Signal Generator: Two Signal generators and oscilloscopes (Keysight EDUX10022G, and HP 3312A Function Generator).
High-Temperature Oven: CM Furnace 1712FL 1700C.
Cameras: High-resolution and High-Speed Video (PhotronTM Fastcam AX200) cameras for image collection and DIC (Digital Image Correlation) analyses.
High-Frequency Transducers: Variable frequency ultrasound source consisting of piezo-electric crystals and a stainless-steel housing for the crystals.
Ozone generator: Ozone is produced by passing air through ozonator (Model T Series, Welsbach Ozone System Corporation, USA). Ozone is extremely hazardous to humans and hence all experiments are conducted inside a fume hood. We have purchased an ozone detector to determine fugitive emissions (portable ozone sensor Eco sensor model A-21ZX).
Nano-bubble generator: The nano-bubble will be generated with micro-nano bubble nozzle (Model BT-50FR, Riverforest Corporation, USA). The ozone gas is introduced to the inlet of a sprinkler/utility pump (Model 3YU60A, Dayton, USA) to produce ozone nano-bubbles.
