A review on reduced environmental impacts of alternative green concrete productions

Abstract

Concrete is being recognized for its environmental benefits in support of sustainable development. In response to growing environmental and economic forces, regulatories, engineers and owners are seeking efficient concrete solutions that conserve non-renewable resources. Global demands for regulating concrete waste arise from the growth of these environmental and economic issues. Thus, the concept of green concrete as an eco-friendly alternative to conventional concrete has been emerging. This publication seeks to demonstrate how concrete contributes to future generations' sustainable development, and will be of interest to policy makers, contractors and clients, as well as others involved with the design, construction or operation of buildings and infrastructure. The main objective of this study is to identify key sources contributing to CO2 emissions from concrete and compare 1) traditional concretes with green concretes, 2) concretes produced with blended cements, and 3) fly ash used as replacement of cement, in order to diminish the environmental impact of the concrete production. © 2020, IGI Global. © 2022 Elsevier B.V., All rights reserved.
