Earning carbon credits from using reduced-cement concrete

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)

Developing a 3D concrete printing technology that improves efficiency

The Japanese construction industry is encountering serious problems, such as a lack of technicians and productivity issues caused by smaller workforces.

(05)

Achieving a concrete life cycle with zero waste and reduced CO2 emissions

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)

A new, quicker way to construct domed buildings

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)

Joint research leading to greater carbon negativity

Together with Nippon Concrete Industries Co., we are developing carbon-negative concrete solutions that can greatly reduce the output of CO2.

(02)

Creating a more sustainable concrete-manufacturing cycle

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)

Promoting the use of reduced-cement concrete

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.

CARBON UTILIZED CONCRETE

Cutting CO2 in the air through concrete—
a new way to make the world more sustainable

CUCO is a consortium of 55 companies, universities, and research institutes that includes Kajima, Denka Co., and Takenaka Corp. It is involved in the development of concrete materials, manufacturing processes, applications, and evaluation methods to help achieve an ambitious goal: carbon neutrality by 2050. CUCO is financed by the NEDO* Green Innovation Fund.
