Abstract:
For low-carbon concrete mixtures, where high SCM contents (>40%) are employed, one of the primary challenges that need to be addressed is the low early-age strength. Without sufficient early-age strength, the construction schedule can be jeopardized. One approach to improve and potentially enhance early-age strength is that of nucleation seeding. Introduced in the late 2000s, C-S-H seeds have been known to accelerate and enhance hydration kinetics. Today, several commercial admixtures based on these C-S-H seeds are available in the market. In this talk, I will share our latest results with some of these commercially available C-S-H seeds – both from the lens of lab testing as well as field implementation. Finally, in addition, I will briefly touch upon newer lab-based, synthetic versions that can be potentially used as strength enhancers in the future.
