Industry First: Accelerating Decarbonization from the Foundation. Mitani Sekisan's 'Hybrid Kneading Method' Evolves

Mitani Sekisan Co., Ltd., a leading company in concrete piles, has introduced a new technology that allows for the direct on-site mixing and utilization of 'blast furnace slag powder,' an industrial byproduct, into the cement used in its flagship 'Hybrid Kneading Method.' The company has received certification from the Minister of Land, Infrastructure, Transport and Tourism. By introducing this technology, the company not only reduces CO2 emissions derived from cement by approximately 60% compared to conventional methods but also provides flexible construction and stable quality tailored to site conditions, contributing to the development of the circular economy market. Currently, the 'pre-boring method' is the mainstream for pile foundation work, which requires large amounts of cement, leading to high CO2 emissions. The evolved 'Hybrid Kneading Method' replaces part of the cement with blast furnace slag powder, balancing environmental performance and construction quality. Key features include a 60% CO2 reduction, optimized logistics by on-site mixing, stable quality during summer, and flexible material selection. This offers benefits such as improved environmental ratings, alignment with SDGs, and proven reliability for design firms and general contractors.
