Revolutionizing Construction: Mitani Sekisan's Hybrid Nailing Technology

In a remarkable stride towards sustainability in the construction sector, Mitani Sekisan Co., Ltd., based in Fukui, Japan, has unveiled an innovative technique called the "Hybrid Nailing Method." This method is poised to transform the way concrete piles are laid and aims to accelerate carbon neutrality within the industry by significantly reducing CO2 emissions right from the foundation level.

Advancements in Construction Techniques

Traditionally, the process of installing concrete piles involves drilling into the ground and injecting cement milk—a mixture of water and cement—before inserting the concrete piles. This prevalent method, known as pre-boring, requires massive amounts of cement, contributing to significant CO2 emissions during production. With environmental concerns escalating, the need for a more sustainable alternative became paramount.

With the introduction of the Hybrid Nailing Method, Mitani Sekisan has achieved a groundbreaking innovation by incorporating industrial byproducts, specifically fine granules of blast furnace slag, into the cement mix. This new technology has been recognized by the Ministry of Land, Infrastructure, Transport, and Tourism, receiving certification (Certification Number: TACP–0707 and others).

Key Features of the Hybrid Nailing Method

1. Up to 60% Reduction in CO2 Emissions

The Hybrid Nailing Method replaces a portion of conventional cement with blast furnace slag powder, a byproduct of steelmaking. Utilizing a unique formula called “Post-Mixed Binder” that incorporates both JIS-compliant cement and the slag powder, Mitani Sekisan boasts a CO2 emission reduction of approximately 60% compared to standard Portland cement mixed operations. This makes it a trailblazing eco-friendly construction technique within the industry.

2. On-Site Planting Reduces Logistics Risks

By allowing the blending of multiple materials directly at the construction site, there is no need to transport pre-mixed materials from intermediate sites. This optimizes logistics by minimizing transport vehicle trips, leading to better efficiency, reduced traffic congestion, lower logistics costs, and decreased emissions associated with transportation.

3. Consistent Quality even in Summer Conditions

Cement hydration generates heat, which can complicate quality control in high-temperature conditions during summer. The Post-Mixed Binder reduces the amount of cement used, helping to control heat generation and maintain consistent quality during summer installations.

4. Flexible Material Selection for Optimal Results

This method enables flexibility not just with the Post-Mixed Binder but also in the choice of JIS-compliant cement (including blast furnace cement). Depending on the project's specific conditions, environmental targets, and material availability, operators can select the most suitable materials to achieve desired outcomes.

Benefits for Design Offices and General Contractors

Mitani Sekisan's new method offers substantial advantages for design firms and contractors looking to improve their environmental credentials:

• - Enhanced Environmental Rating: The ability to provide specific figures on CO2 reduction helps projects align with environmental certifications like CASBEE.
• - Social Responsibility Through SDGs: The method illustrates a commitment to circular economy principles by reusing industrial byproducts.
• - Reliable and Trusted Technique: With government certification, this method assures clients of its compliance and effectiveness.
