Nano-titanium dioxide to enhance CO2 uptake by concrete

CO2 use in concrete as a curing agent is a novel technology. Current processes can use upto 7-10% of CO2 during various concrete making stages. Addition of small amounts of nano-titanium dioxide can double up CO2 injection into the process by decreasing the size of calcium hydroxide molecules.
