BASF’s Master X-Seed 55 admixture improves early- and late-age strength development in concrete. This technology is a stable suspension of synthetically produced crystalline calcium silicate hydrate (CSH) nanoparticles that facilitate the growth of CSH crystals between cement grains and improve the overall hydration of portland cement. The technology’s strength-enhancing property permits a reduction in the total cementitious material content of a given concrete mixture while maintaining the concrete’s compressive strength.
Master X-Seed 55 admixture allows concrete producers to expand the performance space of a given concrete mixture and optimize the cementitious content. In addition, this new specialty admixture provides a strength safety factor, permits earlier stripping of forms to improve production efficiency, and promotes sustainable construction. It is recommended for use in ready-mixed and precast concrete, Green Sense Concrete (environmentally-preferred concrete) and Self-Consolidating Concrete (SCC).
