Investigations on the performance of concrete made with blended finely milled waste glass

الملخص EN

Non-recyclable waste glass, which is produced from fluorescent lamps factories, constitutes problem for solid waste disposal in various countries worldwide.

Thereby, the accumulation of waste glass in the plants without being used represents not only a significant loss of money and energy by occupying a big area from plants but also a negative impact to the environment.

This study is considered a significant interest in the development of environmentally friendly concrete with waste glass.

Using waste glass as a construction material is a good way to help the environment through grinding and using it as a partial replacement of cement by weight in concrete.

Five different concrete mixes with various percentages of finely milled waste glass (FMWG) were prepared.

The test results showed that the FMWG has a pozzolanic characteristics and using it as a mineral admixture in concrete, had a bad effect on workability, but improved considerably mechanical properties of concrete at later ages and 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 the FMWG content.
