Abstract

Nowadays, the requirements related to sustainable development and environmental protection have motivated most researchers of materials science, chemistry and environment, as well as civil and architectural engineers to use waste materials in the construction concrete structures. One of the most important environmental issues of concrete structures is cement consumption. The global warming and the increase in the concentration of greenhouse gases have prompted the researchers to use new materials such as polymers or pozzolans in order to reduce the consumption of cement and the carbon footprint caused by the production of concrete from concrete fillers and additives. The main goal of this article is to introduce environmentally friendly concrete using pozzolans (slag, silica fume, and fly ash). For this purpose, different tests were conducted with four different mixing plans and various parameters including service life of concrete and compatibility with the environment were calculated using Life-365 software. The results indicate that the use of pozzolans in the amount of 40% of the weight of cement, so that the amount of carbon black is 15% and slag is 25%, will have the best performance in terms of compatibility with the environment in such a way that the permeability decreases and the service life has increased.
