Design of 3D printable concrete based on the relationship between flowability of cement paste and optimum aggregate content

Cement & Concrete Composites, 2019
This paper deals with the mixture design of 3D printable concrete (3DPC) based on the theoretical analysis of the yield stress of mortar. It has been found that there is a linear relationship between the flowability of paste and optimum aggregate content

Classifying Powder Flowability for Cold Spray Additive Manufacturing Using Machine Learning

2020 IEEE International Conference on Big Data (Big Data), 2020
Metal powders are used as feedstock in a variety of manufacturing methods, wherein the metallic particulates may be deposited upon a substrate, spread upon a build plate, or melted layer-by-layer.

Flowability of Electrolytic Copper Powder

Materials Science Forum, 2005
The surface structure of powder particles, which allows free flow of copper powder, was examined. It has been shown that a sufficiently dense surface structure which permits free flow will be obtained if apparent density is higher than 2.2 – 2.3 g/cm3.

Genotoxic biomonitoring of flowable and non-flowable composite resins in peripheral blood leukocytes

Acta Odontologica Scandinavica, 2012
Composite restorative materials represent one of the most important groups of materials in contemporary dental practice. However, their incomplete polymerization may lead to monomer-induced genotoxicity. The objective of this study was to evaluate the genotoxicity of three flowable (Filtek Supreme XT Flow, Tetric EvoFlow, Gradia Direct Flo) and three ...

Melamine cyanurate surface treated by nylon of low molecular weight to prepare flame‐retardant polyamide 66 with high flowability

Fire and Materials, 2019
In the present research, a nitrogen‐based flame‐retardant, melamine cyanurate (MCA) was surface‐treated with low‐molecular‐weight nylon through a solvent process to further improve its flowability and dispersion. The surface energy and flow energy of the

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.

Comparison of flowable bulk-fill and flowable resin-based composites: an in vitro analysis

Clinical Oral Investigations, 2016
Flowable bulk-fill resin bonded composites (RBCs) are supposed to show improved abrasion resistance and fracture toughness in comparison to flowable conventional RBCs.Specimens of eight flowable RBCs (5× flowable conventional, 3× flowable bulk-fill) were fabricated for testing relative fracture toughness (SENB), relative three-body wear, the Vickers ...
