A Classification Review on Green Concrete

Abstract

This paper is a short review of green concrete as claimed per latest related available literature. Green concrete refers to concrete mixture with lower carbon footprint, during its total life cycle, as compared to ordinary concrete mixture. This may be due to its composition of one or more green component (s) such as silica fume or fly ash, or to its capacity, as a building material, to reduce one or more pollutant (s) and/or to any other sustainable concrete procedure such as reduced raw materials depletion. A leading Italian concrete production group claims the provision of a new air scrubbing green concrete combining all of the above techniques. The claimed air scrubbing is based on a photocatalytic principle whereby natural or artificial light activates an oxidation process converting noxious pollutants into harmless compounds. Green concrete promotes sustainability in a creative way; thus, improving global human health.
