Abstract

Non-recyclable waste glass, which is produced from fluorescent lamps factories, constitutes a problem for solid waste disposal in various countries worldwide. Thereby, the accumulation of waste glass in the plants, not being used, represents not only a significant loss of money and energy by occupying a big area from plants but also a negative impact on the environment. This study is considered of significant interest in the development of environmentally friendly concrete containing waste glass.

Using waste glass as a construction material is a good way to help the environment following grinding and its use in concrete as a partial replacement for cement by weight. Five different concrete mixes with various percentages of finely milled waste glass (FMWG) were prepared. The test results showed that the FMWG has pozzolanic characteristics and using it as a mineral admixture in concrete, had a bad effect on workability, but improved considerably the mechanical properties of concrete at later ages. The optimum percentage of FMWG that gives the maximum values of compressive, splitting tensile and bond strengths is 10%. Results also showed that expansion due to alkali-silica reaction was minimized obviously by increase in the FMWG content.
