Abstract:
A shrinkage-reduced, self-consolidating, high-performance concrete that can be used for production of thin elements with high aesthetic, mechanical, and durability performance requirements was recently developed. The prepackaged dry mixture comprises Aalborg White® portland cement, ground carbonate, and reactive metakaolin. The combination results in high performance as well as a low CO2 footprint.
