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.
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
