Leading the feld work on behalf of the American Society for Concrete Contractors are Dr. Ward Malisch, principal investiga- tor, and ASCC Technical Director Dr. Bruce Suprenant. The students are part of the Senior Concrete Research class of MTSU's Dr. Heather Brown, project co-investiga- tor. The class has been evaluating different methods of measuring the area of air voids (bugholes) on surfaces based upon time needed for measurement; cost of measuring equipment; and, different methods' accura- cy and precision. The U-shaped structures will serve as permanent control surfaces on which multiple measurements can be made using several methods. CIM students assist ASCC, ACI, RMC-backed surfaces research ACI Committee 347, Formwork for Con- crete's "Guide to Formed Concrete Surfac- es" (ACI 347.3R-13) defnes four quality levels of formed concrete surfaces and provides methods to achieve and evaluate them. The project was initiated to address ASCC members' concerns with Guide recom- mendations for specifying concrete surfac- es. Additional funding has been provided by the Ready Mixed Concrete Education and Research Foundation and American Concrete Institute's Concrete Research Council. The ASCC Education, Research and Development Foundation was chartered in 1989 to advance the quality and productivity of concrete construction.
