Dr. Christian Meyer to Test Concrete Masonry Units with Recycled Glass Aggregate

Newsbriefs

Dr. Christian Meyer of Columbia University has signed a 2-year, $230,000 research contract with the New York State Energy Research and Development Authority to test concrete masonry units made with recycled glass as the aggregate. Glass will be provided by the New York City Department of Sanitation, which will soon be collecting over 100,000 tons per year of mixed- color waste glass. (All 27,000 tons the City collected in 1993 went into glassphalt, but supplies are expected to quickly outstrip demand as collection increases.) In addition to reducing the landfill space needed for glass disposal, the “glasscrete” CMUs could reduce the environmental impact caused by mining natural aggregate. Barrasso & Sons, Inc. of Islip Terrace, New York will manufacture blocks for the tests.
