Glass Concrete

The use of crushed waste glass as aggregate in concrete is problematic because of the chemical reaction between the alkali in the cement and the silica in the glass. This alkali-silica reaction (ASR) creates a gel, which swells in the presence of moisture, causing cracks and unacceptable damage of the concrete. Research at Columbia has focused on a basic understanding of the ASR phenomenon and on searching for ways to avoid it or to mitigate its detrimental consequences.
