Effects of Glass Powder as a Partial Cement Replacement on Mechanical Properties and Behaviour of Concrete

Concrete is the most used construction material all over the world and cement as the most valuable component in concrete affects both concrete price and quality. On the other hand, cement manufacturing industry is one of the carbon dioxide producing sources, that is caused global warming. However, using the waste materials and byproducts as cement replacement materials become an attractive alternative because it helps to reduce the cost of concrete and cement manufacturing, also has numerous indirect benefits such as saving energy, reducing landfill cost and protecting the environment from possible pollution effects. Nowadays, waste glass is one of the most polluting waste materials for the world environment. For this reason, in this thesis, the glass powder (GP) of waste glass was examined as a partial cement replacement material in concrete with five different proportions (0%, 10%, 20%, 30% and 40%) for three water-binder ratios (w/b) (0.4, 0.5 and 0.6). Finally, experimental results indicated that GP can be used as a cement replacement material and it can improve both physical and mechanical properties of concrete for all three different w/b tested in this study.
