A study of the influence of aggregate grading on concrete penetrability
… properties of hardened concrete. The aggregate particle size distribution is usually selected so as to achieve a particle packing density that is equal to or near the maximum, which is seen as optimal for strength and durability. However, the influence of aggregate grading on durability apart …

Experimental and numerical investigation of steady-state and transient ultrasound directed self-assembly of spherical particles in a viscous medium
… a standing ultrasound wave field to organize particles dispersed in a fluid medium into specific patterns. The ability to tailor the organization and packing density of spherical particles using ultrasound DSA in a viscous fluid medium is crucial in the context of (additive) manufacturing of …

Simulation of packed column jigging
… finely disseminated particulate materials. The packing materials in the jig divide the column into a large number of virtual cells. Each cell performs the similar separation action. A model about the movement of a particle in the packed column jig was derived to interpret the separation …

Colloidal properties of sugar particle dispersions in food oils with relevance to chocolate processing
… on the interactions between fine sugar particles dispersed in different triglyceride oils has been investigated at a range of volume fractions. Four techniques were applied: rheology. sedimentation, light microscopy and adsorption. Eight different types of food oil were used: sunflower …

The Influence of Amorphous, Sub-Micrometer Silica Particles in Cement Pastes and Mortars with Very Low Water-to-Cement Ratios (Ultra-High Performance Concrete)
… influence of amorphous, sub-micrometer silica particles in UHPCs. The present literature is equivocal about whether silica enhances clinker hydration due to its dissolution and subsequent pozzolanic reaction to calcium–silicate–hydrate phases (C–S–H phases) and/or due to a heterogeneous …

Powder packing optimisation for clinker reduction in concrete
… The optimisation of powder (materials < 125 µm) packing, using filler materials with varying fineness, was identified to potentially increase clinker efficiency. The optimisation undertaken was the maximisation of powder packing density but without adversely affecting workability. The …
