From the conclusion of the research, it can be seen that it is necessary to future study the influence of flowability on the performance of flowable SFRC.
(1) Current test methods for determining mechanical properties of SFRC are recognized as partially unsuitable. The development of new test method is required to accurately determine the performance of SFRC.
(2) Vibration time can have a large impact on the distribution of the steel fibers, especially when the slump of SFRC is above 160 mm. Over-vibration will lead the steel fibers to sink towards the bottom of specimens. Control of the vibration time could be a key to control the distribution of the steel fibers.
(3) Although formulas for calculating mechanical performance of SFRC are proposed in this research, there is not sufficient data to justify whether these formulas can be used for all situation. Experiment should be carried out to provide data for verifying the formulas.
(4) It is quite clear that the change in flowability will influence significantly on the mechanical properties of SFRC. However, with the data gathered from this research, it is not possible to propose a formula which is able to calculate mechanical properties directly using flowability. Further research is required to determine if such a relationship can be determined.
