We’re checking in with high blend cements, geopolymer cement and a new technology used by LafargeHolcim that uses CO2 instead of water in the curing process
A number of green concrete additives have been developed that reduce the amount of cement needed to make concrete, from plastics to iron slag and even carrots.
Cement creates more carbon emissions than every car in the world combined, but Beyond Zero Emissions has cooked up a plan for Australia to lead the world with a zero carbon cement industry. And one that could help reverse job losses through the closure of coal plants.
Cement production is the third-most polluting industry in terms of greenhouse gas emissions, behind chemicals/petrochemicals and iron and steel.
A new formula for cement could drastically reduce carbon emissions in the construction sector while improving the strength and durability of concrete, researchers say.
