A clean and sustainable CO2 storage method in construction materials

Abstract Production of building materials emits 11% global carbon dioxide (CO 2 ) emission. The greenhouse gas emission from the construction industry has been tried to mininmize early 1980s; but after four decades development, it is not fully sustainable. Cement second most consumed material in world, water and cement production contributes for 8% CO We produced a greener abundantly available waste: fly ash, blast furnace lag, rice husk ash significantly minimize Discarded aluminium foil becomes one landfilling waste that high potential recycling. On other hand, carbonation curing method stores significant amount into with lesser cost energy compared commercial sequestration. Therefore, we incorporate improve engineering environmental performance cement. changes when using gaseous (gCO supercritical (scCO found scCO condition achieves higher compressive strength yielded stronger barrier against leaching. Hence, this cured can be widely used underground applications, where heavy metal leaching critical issue. Projections show our reducing by 55% Portland direct costs 35%. Also, ultimately reduces hydrogen demand recycling aluminium, which releases pure during process, effect annual 35 million tonnes alone. Adopted globally, system would permanently store 72 stable composite annually. whole, requirement manufacturing future energy, gas, as product.
