Waste Glass Powder “An Alternative of Cement in Concrete”: A Review

Cement plays a vital role in concrete production; as a binding agent, it holds together the aggregates in concrete. Manufacturing of cement and glass causes depletion of natural resources and endangerment of the environment. Both the glass and cement industries are energy consumers and are responsible for hazardous greenhouse gases, particularly  and nitrogen oxides. The contribution of the cement industry toward  emissions is 5% globally, and it is estimated that one ton of cement production produces 0.9 to 1 ton of _. The rising population rate, which is a concern today, necessitates proper construction and infrastructure. This leads to more production of cement and glass and as a result, millions of tons of glass waste are produced every year globally and deposited directly into landfills without being recycled. The global Waste Glass (WG) production was estimated to be over 130 million tons in 2005. Because of its non-biodegradable nature, it is a huge burden on landfills, especially in metropolitan areas. At the same time, it exhibits pozzolanic behavior in finely ground form. To overcome these problems and to use them as a source, the concrete industry provides a better solution. Adaptation were taken to use it as an out of the ordinary to cement in concrete and examine its effects on concrete in both fresh and hardened states. According to the study, the mechanical characteristics of Waste Glass Powder (WGP) concrete are influenced by particle size and percentage replacement. This review is aimed at studying glass powder concrete.
