The reuse of waste glass poses a major problem in large municipal areas of the United States. Post-consumer glass is often mixed-color and commingled with plastics and metals, contaminated with other materials like ceramics and organic matter and partially broken. This reduces its value and complicates the ability to achieve the cullet specifications of bottle manufacturers or other markets such as the construction industry. Most of these markets make little use of the inherent chemical and physical properties of glass, therefore its market value is very low. A major research effort has been underway at Columbia University for a number of years, to develop new applications for waste glass as an aggregate for concrete. Extensive studies were undertaken to solve the alkali-silica reaction (ASR) problem. Specific products such as paving stones, concrete masonry blocks, terrazzo tiles, and precast concrete panels are close to commercial production. This paper discusses the various steps that need to be taken by recyclers to collect the glass, separate it from the other materials, clean it and crush it to obtain the appropriate grading to meet the specifications for specific applications. Glass is unstable in the alkaline environment of concrete and could cause deleterious alkali-silica reaction problems. This property has been used to advantage by grinding it into a fine glass powder (GLP) for incorporation into concrete as a pozzolonic material. In laboratory experiments it can suppress the alkali-reactivity of coarser glass particles, as well as that of natural reactive aggregates. It undergoes beneficial pozzolonic reactions in the concrete and could replace up to 30% of cement in some concrete mixes with satisfactory strength development. The drying shrinkage of the concrete containing GLP was acceptable.
