Experiences in the development of Ultra High Performance Concrete found a very high flowability in concrete with low water powder ratio. Because of the high viscosity of the cement paste, compaction was necessary. To improve the compaction characteristics of the concrete the idea of adding coarse aggregate was developed. The first tests showed a good workability of the fresh concrete and a good...

Fruits are essential components of a healthy diet contributing to the prevention different diseases. Nevertheless, their consumption is limited among population for reasons convenience, others. High-quality products obtained by freeze-drying; however, dehydrated fruit presents physical stability problem associated with glass transition its amorphous matrix. A common technique prevent rubbery st...

Abstract In order to improve the flowability of lithium hydroxide powder, powder in a company was selected under conveying condition. The degree circularity used quantitatively characterize micro-morphology and influence particle size on studied by angle repose method, HR method Carr index method. results show that gets better with increasing size. But fine particles (≤ 100μm) is poor, while me...

Powder flowability affects dynamic powder behavior during additive manufacturing and varies depending on particle size distribution, morphology, surface features. In this study, Inconel 718 alloy powders were prepared by gas atomization (GA), plasma (PA), rotating electrode process (PREP). The was experimentally evaluated the avalanche angle. With help of numerical simulations, individual effec...

Abstract By offering a powder that ensures the healthy value of fruits, proper flowability and adequate viscosity after rehydration, there could be an opportunity to promote fruit consumption. The particle size is critical importance with regard properties powder. But separation product by usually associated compositional changes. In this study, orange same composition but different was compare...
