The Structural and
Concrete Materials Laboratory includes: an Instron 8500 Series Servohydraulic Testing
System that is used for the controlled testing of various materials in a closed-loop
system; an acoustic emission data acquisition system; a Concrete Analysis System (CAS
2000) for petrographic analysis of hardened concrete; a digital image analysis system;
scanning electron and quantitative microscopes; a Deluxe Super
L Tinius Olsen Universal Testing Machine, 400,000 lb capacity, digital type for testing
tension and compression structural elements. Instrumentation available at the laboratory
ranges from simple digital indicators to a high speed computer-controlled data acquisition
