Greening the Building Industry: Kajima’s Innovative Low-Carbon Dome for the 2025 Osaka-Kansai Expo

Kajima Introduces Innovative Low-Carbon Concrete Technology for Osaka Expo Dome

Kajima Corporation recently announced a major reduction in carbon dioxide (CO2) emissions for the construction of a concrete dome for the 2025 Osaka-Kansai Expo. The company plans to use a type of low-carbon concrete that reduces emissions by 70% compared to traditional building methods. This eco-friendly dome will be constructed in the West Gate Zone of the expo venue and will serve as an exhibition space on environmental education.

The construction of the dome is set to begin in April and be completed in November 2024. The dome will be made of reinforced concrete, standing 5.45 meters tall with an oval shape and a diameter of 23 by 18 meters. By utilizing low-carbon concrete along with a technology that absorbs CO2 during manufacturing, Kajima expects to achieve a significant reduction in CO2 emissions.
