The Concrete Laboratory is located in 1167 Learned Hall. The Laboratory is equipped to run standard tests on cement, aggregates, and concrete. The laboratory is operated as both a teaching and research facility. Equipment is available to test concrete aggregate for deleterious behavior, including alkali silica reactivity, and to measure aggregate properties as they affect mixture proportioning. Freeze-thaw equipment is available for running tests under both Procedures A and B of ASTM C666. A walk-in freezer is used for scaling tests. Concrete is cured under controlled temperature and humidity in the lab's curing room. Two hydraulic testing machines, with load capacities of 180 tons (400,000 lb), are used for concrete strength determination.
