Sustainable concrete from Kajima
Sustainable concrete
from Kajima
Imagine using CO2 to build our cities—and our future.
There’s no easy answer to how to make our world sustainable.
But at Kajima, we’re developing our own answers through concrete.
This two-minute video will give you a better idea of what we have in store.

Stay-In-Place formwork made of CO2-SUICOM, a carbon-negative concrete that emits practically zero or less CO2 during concrete production, was applied for the first time to highway bridge pier construction. CO2-SUICOM is a concrete that can absorb and fix CO2 within its interior during the manufacturing process.

An innovative system that reduces concrete waste generated at construction sites to zero has been put to practical use at the construction site of a large-scale production facility in Kumamoto Prefecture.
(07)
By using reduced-cement concrete, we were able to greatly lower CO2 emissions during the construction of Dommy Minami-Nagasaki Annex, a residential building.
(06)
The Japanese construction industry is encountering serious problems, such as a lack of technicians and productivity issues caused by smaller workforces.
(05)
Usually at a construction site, a small amount of concrete goes unused and is either discarded or returned to the ready-mix concrete plant it came from.
(04)
Through our technology-sharing partnership with US-based Dome Technology, we have developed a new construction method that we call KAJIMA next Technology DOME, or KT Dome.
(03)
Together with Nippon Concrete Industries Co., we are developing carbon-negative concrete solutions that can greatly reduce the output of CO2.

Working jointly with Sanwa Sekisan Co. and Tokai University, we have developed both Cem R3—a cement manufactured from recycled, unused ready-mix concrete that would otherwise be sent back to the plant it came from—as well as Eco-Crete R3, a concrete made from this cement.
(01)
In 2014, we collaborated with one university and seven companies to develop Eco-Crete ECM, a reduced-cement concrete that can be manufactured with over 60% less energy and CO2 emissions than standard concrete.
