Characterization optimization of flow properties

Moreover, the optimization procedure revealed that the best performance in terms of maximum mechanical properties and impact resistance, as well as the minimum cost, was achieved in the mixture reinforced with 1.

In other words, both static and dynamic characterization techniques must be employed to completely understand the flow properties of a powder and predict how it will behave under different process conditions.

Graphical abstract Different powder characterization techniques have been investigated to address their suitability for predicting powder behaviour in various applications. In addition, the statistical study showed that the two-parameter Weibull could be adopted to analyze the distribution of the first crack FC and ultimate crack UC impact resistance.

It was also found that results from static and dynamic characterization do not necessarily agree, where fine powders that showed good fluidization performance also displayed increased agglomeration, and vice versa.

The fresh state properties were assessed in terms of flow slump diameter and T It was found that characterization techniques that were more dynamic such as fluidized bed expansion were best suited for predicting the fluidization performance while characterization techniques that were more static such as cohesion were better for predicting agglomeration.

Then, a statistical method based two-parameter Weibull and an optimization procedure were executed on the collected experimental results. Fresh and hardened properties of the fiber reinforced self-consolidating concrete were assessed, considering total fiber volume fraction of 1.

VolumeIssue 315 SeptemberPages Characterization of powder flow: Conflicting results were found between static and dynamic techniques, and it is proposed that multiple characterization techniques ranging from static to dynamic must be performed to fully understand the properties of a powder.

Moreover, the hardened state properties of specimens were characterized by using the ultrasonic pulse velocity, the compressive strength, the splitting tensile strength, the flexural strength, and the impact resistance.

This suggests that flow properties are dependent upon the stress state and that no single technique is suitable for the full characterization of a powder.

The results showed an enhancement of mechanical properties and impact resistance in self-consolidating concrete by the addition of fiber, which was significantly governed by fiber type, content, and combination.The exopolysaccharides produced by the cyanobacterium Lyngbya stagnina have been characterized.

Maximum amounts of EPS ( µg EPS ml −1 culture) were obtained during the stationary phase of growth and rate of EPS production was maximum during late phase of growth.

Moreover, the optimization procedure revealed that the best performance in terms of maximum mechanical properties and impact resistance, as well as the minimum cost, was achieved in the mixture reinforced with % recycled steel fiber (Rst) as mono-fiber and the mixture reinforced with 1% industrial steel fiber and % recycled steel fiber.
