Keen on lower carbon alternatives to portland cement-only binders, the U.S. Department of Commerce-backed NIST has published Technical Note 1906, Minimizing Paste Content in Concrete Using Limestone Powders – Demonstration Mixtures. Researchers cite target performance levels in concrete mixtures with up to 28 percent lower portland cement content using a binary blend with limestone powder.
