Sustainable concrete : overview of recent developments and applications

The purpose of this paper is to present the latest developments of the area of sustainable concrete. The paper will highlight some of the technologies that suit the Libyan case, to help decision-makers in Libya to move towards efficient and sustainable structures. One of the recent trends to shift towards more green and sustainable concrete is by utilizing alternative aggregates. The recycling of construction materials such as concrete or non-construction materials such as glass and scrap tires, or even some by-product materials such as steel slag, then the use of these materials as alternative aggregates in sustainable concrete. The use of alternative raw materials from waste or by-products of different industries, and the replacement of conventional fuels with alternative fuels, are other trends to advance the sustainability of concrete and better the cement industry. Nevertheless, most of these technologies are still facing different obstacles to be adopted in all civil engineering projects.
