Durability Properties of Mortar Overlays with Glass Aggregates
Sustainable building materials are the future of the construction industry. Specifically, eco-friendly cementitious materials that are mechanically sound and durable are desired as the majority of the world’s infrastructure, including roads and bridges, are made with concrete. Since the durability of cementitious materials can greatly affect the performance of a structure, it is important to evaluate the properties of these new materials. In this study, cement mortar overlays containing recycled glass aggregates were investigated. Particularly, the focus of this study was to determine the benefits of using glass in reducing early-age cracking of mortar overlays. The rate of plastic shrinkage crack formation and overall crack area was quantified for specimens subjected to set environmental conditions. In addition, the rate of absorption, which influences the serviceability and structural performance of a structure, was also evaluated. The findings of the experimental study suggest that glass aggregates are effective in reducing the rate of crack formation by 98% when full glass replacement is used. Furthermore, at full glass replacement, the initial and secondary rate of absorption was found to decrease by 31% and 63%, respectively.
