About awarded research

"A New Concept of Calcium Carbonate Concrete using Demolished Concrete and CO2"

Currently, carbon neutralisation is an urgent issue in the concrete sector because of the high CO2 emissions in concrete production. This is the first paper from the NEDO Moonshot Project. Prof. Takafumi Noguchi is the PM, proposing a completely new calcium carbonate concrete, using calcium carbonate as the binder. This paper, led by Professor Ippei Maruyama, who had been conducting research on carbonated concrete in the geological field, hypothesized a reaction mechanism and demonstrated that a hardened body could be produced using calcium carbonate as the binder. This research is a technology that, when put into practical use, will enable significant reductions in CO2 emissions and resource input because it uses concrete waste, fixes CO2 in the air, and ultimately makes the material itself recyclable.
