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.

TL;DR: In this article, the waste generation during several Dutch residential construction projects has been quantified and analyzed in detail, and it was shown that about 1-10% by weight of the purchased construction materials, depending on the material, leave the site as waste.

TL;DR: In this paper, experiments and theories on self-compacting concrete are discussed, where the packing behavior of the powders (cement, fly ash, stone powder) and aggregates (three sands and gravel) used are analyzed in detail.

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.

TL;DR: In this article, the authors presented the effect of nano-silica on the hydration and microstructure development of UltraHigh Performance Concrete (UHPC) with a low binder amount.
