DEM simulation of SCC flow in L-Box set-up: Influence of coarse aggregate shape on SCC flowability

, 2020
Coarse aggregate are one of the main components of self-compacting concrete (SCC) and the size, shape, and grading of coarse aggregate can lead to different characteristics of SCC.

Coordinated adjustment and optimization of setting time, flowability, and mechanical strength for construction 3D printing material derived from solid waste

, 2020
Construction 3D printing (C3DP), as a green building concept, yields savings in terms of time, material, and labor costs and, hence, has become increasingly popular in recent years.

Using fractal dimension and shape factors to characterize the microcrystalline cellulose (MCC) particle morphology and powder flowability

, 2020
The flowability of microcrystalline cellulose is related to its particle morphology and structure, but this relation is difficult to characterize quantitatively, due to irregularity in particle shape. This study uses fractal dimension combined with shape

Combined treatment of electrical and ethylene-vinyl acetate copolymer (EVA) to improve the cold flowability of waxy crude oils

, 2020
Flow assurance issues related to wax precipitation, are one of the most challenging problems in the pipeline transportation of waxy crude oils. Flowability of waxy oils can be improved by suitable pour point depressants (PPDs).

The flowability of ice suspensions

Journal of Rheology, 2005
Ice slurries show great potential for use in low energy refrigeration and cold storage systems but their transport properties and ice particle agglomeration are not well understood. Determination of the rheology of ice slurries has proved very difficult mainly due to the low viscosity carrier fluids currently used.

Hydrothermal carbonization of yard waste for solid bio-fuel production: Study on combustion kinetic, energy properties, grindability and flowability of hydrochar.

Waste Management, 2019
Yard waste is either dumped or is being openly burned to get rid of it, instead of using it as a valuable renewable energy source. In this study, hydrothermal carbonization of yard waste was conducted to valorize it as a solid bio fuel, using a batch ...

Flowability characterization of nanopowders

Powder Technology, 2015
Abstract The applications of nanopowders are increasing significantly over the last years. In most of these applications, the flow behavior of the nanopowders seems to be a complicated, multiparametric but critical issue for the proper design of the processes.

How does adsorption behavior of polycarboxylate superplasticizer effect rheology and flowability of cement paste with polypropylene fiber?

Cement & Concrete Composites, 2019
Nowadays, polycarboxylate (PCE) superplasticizer and polypropylene fiber (PPF) are widely used to improve the flowability and ductility of modern concrete. In this study, the rheology and flowability of cement paste with PPF have been investigated.
