Mix design and properties assessment of Ultra-High-Performance Fibre Reinforced Concrete (UHPFRC)
TL;DR: In this article, the authors addressed the mix design and properties assessment of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) by employing the modified Andreasen & Andersen particle packing model.
Journal ArticleDOI
Development of an eco-friendly Ultra-High Performance Concrete (UHPC) with efficient cement and mineral admixtures uses
TL;DR: In this paper, a modified Andreasen & Andersen particle packing model is used to achieve a densely compacted cementitious matrix, and the results show that the influence of FA, ground granulated blast-furnace slag (GGBS) and limestone powder (LP) on the early hydration kinetics of UHPC is very similar during the initial five days, while the hydration rate of the blends with GGBS is mostly accelerated afterwards.
