- FY2025AdvancedAnnual report
「The Company developed CELBIC, an environmentally friendly concrete made by mixing ground granulated blast-furnace slag, which produces low CO2 emissions during manufacture, into cement, and obtained a performance certificate in 2021. It is also applying this expertise to decarbonize civil engineering concrete structures, with 1 application to date. Going forward, the Company will obtain a revised performance certificate and promote decarbonization.」
