COCOLOW low-carbon precast concrete (blast furnace slag + molten slag)
Precast concrete products formulated with ~40% lower CO2 emissions through high replacement of Portland cement by blast furnace slag and substitution of fine aggregate with molten slag from waste incineration.
Problem solved
High embodied carbon in conventional precast concrete for infrastructure and urban projects; need for drop-in low-carbon alternatives using local industrial byproducts without major process changes.
Application contexts
- urban infrastructure
- civil engineering works
- zero-carbon city projects
- public works requiring quantified carbon reduction
Technical principle
55%+ replacement of Portland cement with blast furnace slag micro-powder (per MLIT low-carbon criteria) combined with molten slag as recycled fine aggregate; optional integration of self-healing bacterial additives for durability.
Typical use cases
- Precast blocks, panels, and secondary products for roads, drainage, retaining structures in decarbonization-focused public or private projects
