Embodied energy in concrete
WebFor example, with concrete, innovation could focus on lowering cement’s carbon footprint or finding an alternative. Cement kilns could utilize alternative methods for heating cement kilns rather than fossil fuels. ... Historic buildings have embodied energy that is lost when a building is demolished. According to a study commissioned by the ... WebIn terms of looking at entirely new materials rather than clay, one can consider concrete brick. Since concrete bricks are not fired, they have less embodied energy. But concrete brick contain about 15% Portland cement—a carbon-intensive material—so the concrete brick greenhouse gas emissions end up being about the same as clay brick.
