Sustainable construction and low-carbon dioxide concrete: Algeria case

Abstract

Climate change seems to have had a notable effect on the environment. Natural disasters such as flooding are occurring more frequently but the human effect on the built environment and transportation is the greatest single cause of greenhouse gas emissions. The construction industry consumes a large amount of energy and natural resources, especially in construction materials. Hence, action is needed to reduce carbon dioxide emissions, increase recycling and the reuse of materials and reduce water consumption. In this paper, the negative effect of the construction industry on climate is examined and remedial actions are proposed. A review of construction-related effects on climate change and sustainable construction is followed by a presentation of the authors' research on low-carbon dioxide concrete. Some examples of actions taken in Algeria to mimimise the effects of the industry on climate through research and practice are given. This mainly includes the use of cement replacement materials, recycling and efficient utilisation of resources.
