According to a recent report by the American physicist organization network, researchers at Michigan State University found that the concrete produced by grinding and mixing waste glass into cement will be stronger, durable and waterproof, and can reduce the landfill of a large amount of waste glass. The energy consumption and carbon dioxide emissions required to build cement at the site, usually at high temperatures. Two related papers were published in the latest "Technology and Management of Solid Waste" and "Building Building Materials" magazine.
This method can replace about 20% of the cement produced by crushing and grinding the glass. "There is a favorable reaction to inject the ground glass into the cement mixture, which improves the basic chemical properties of the cement and makes the concrete more durable," said Parviz, a professor of civil and environmental engineering at the school who has been working on glass-mixed concrete. Durable and not as fast as ordinary cement."
The test site has been in place for three years and is located at the University’s Remaining Storage and Recycling Center, the South Breslin Student Activity Center and the sidewalk outside the Hubbard Hall on the east side of the campus. So far, the test results for this concrete have shown quite good results.
Linda Buma, an energy and environmental engineer at the university, said: “I am very pleased to see that the research done at the university laboratory can be applied to our campus. This concrete does not look too different from standard concrete. The color is a bit lighter, but in most cases it's hard to tell."
“The cement is usually processed at a very high temperature, and the addition of ground waste glass can significantly reduce its energy use and carbon dioxide emissions,” said Parviz.
