MIT CSHub Schedules Public Webinar on New Test Method for ASR
Alkali-silica reaction (ASR) is second to corrosion as the leading cause of the premature deterioration of concrete structures in North America. Dr. Michael Thomas, professor of civil engineering, University of New Brunswick, will present a new test method which was developed in order to better predict expansion in real structures. This was achieved by developing a test where alkali leaching is minimized by placing concrete cylinders in a solution matching the internal pore solution of the concrete under test. Long-term results up to and including 900 days are presented for a number of aggregates and compared to long-term performance data from exposure sites in Austin, Ottawa and Fredericton.
