Blast-furnace-slag low-carbon precast infrastructure blocks
Shikoku Block Industry's precast concrete products made with blast-furnace slag powder as a partial cement replacement.
AI-assisted directory summary. Technical specifications, performance metrics, readiness and compliance labels are unverified unless individually supported and reviewed. Proposed partnership routes do not establish supplier consent, export eligibility, or willingness to sign an NDA. Confirm claims and test conditions with the linked sources and supplier before procurement or citation.
Problem solved
Reduces cement-related emissions in factory-made drainage, retaining-wall and other infrastructure products while preserving a regional precast production route.
Application contexts
- Precast drainage products
- Retaining-wall and block products
- Road and river infrastructure
- Regional low-carbon construction projects
Technical principle
Blast-furnace slag powder, a steelmaking byproduct that can harden similarly to cement after drying and grinding, replaces part of Portland cement in a precast mix. The company reports that mix adjustment was required to address slower early strength and temperature sensitivity.
Typical use cases
- Low-carbon precast drainage blocks
- Slag-containing retaining-wall products
- Project-specific infrastructure precast
Partnership route
How global engineering teams typically engage this asset.
Helpful to include: Product SKU and slag replacement ratio · Required early and later strength · Exposure and durability class · Mould and annual volume requirements · Delivery radius and site logistics · Project carbon-accounting method
