    Conventional concrete is responsible for high greenhouse gas emissions, mostly from the production of Portland cement and the mining of raw materials. However, this impact can be significantly reduced through the use of cement ‘extenders’ (e.g. fly ash, ground blast furnace slag and silica fume), new cements (e.g. geopolymers, magnesium cements), and alternative forms of concrete (e.g
