Sustainability Considerations of Concrete Mixes Incorporating Slag as Partial Replacement of Cement in Concrete in the UAE
The United Arab Emirates (UAE) is one of the largest consumers of concrete in the region due to the enormous number of mega reinforced concrete projects constructed in the country. The harsh weather of the UAE, where temperature may reach to above 45 °C and the humidity at coastal areas up to 100%, requires special attention to the design of the concrete mixes used in these projects to make sure that they meet the strength requirement and satisfy the sustainability condition. To insure the sustainability of the projects constructed in the UAE a local sustainability rating system called “Estidama” was developed by Abu Dhabi Urban Planning Council. The Estidama sustainability rating system is equivalent to the LEED, but tailored to the special culture and climate of the UAE and the region. This system is mainly implemented in the UAE’s capital city Abu Dhabi and gaining more publicity in the region. The main objective of this paper is to evaluate collected concrete mixes implemented in some major projects in the UAE’s based on Estidama’s requirements, and to come up with an optimization process to choose the most sustainable concrete that satisfies the mechanical properties requirements, durability requirements and has the least embodied CO2 emission. This research will concentrate on concrete mixes commonly used in the UAE with emphasises on those incorporating slag as a partial replacement of cement in concrete.
