The negative environmental impacts associated with the usage of Portland cement (PC) in concrete induced intensive research into finding sustainable alternative mixes to obtain “green concrete”. Since principal aim developing such is reduce impact, it imperative conduct a comprehensive life cycle assessment (LCA). This paper examines three different types mixes, viz., alkali-activated (AAC) nat...
