For concrete research, equipment is present for batching, mixing, placing, finishing, and curing small-scale concrete specimens. A local redi-mix company supplies the concrete, in accordance with our specifications, for large-scale specimens. We have over a 10 year working relationship with this company. The laboratory also houses standard equipment for measuring the fresh and hardened properties of concrete. Specific equipment and facilities in the laboratory include 1 fixed and 2 programmable freezing and thawing chambers, light microscopes for assessing material composition and macroscopic damage, an image analysis system, 2 electrochemical impedance spectroscopes, and controlled environmental rooms with associated equipment for measuring creep and shrinkage of materials.
