Fibre-reinforced Self-compacting Concrete: Prediction of Rheological Properties

Abstract [en]

The purpose of this thesis is to investigate the relationship between measured rheology and proportioning properties with particular attention to maximum packing fraction, thickness of fiber lubricating matrix and fiber rotational overlap. This is done by conducting experiments on fresh concrete where the amount of matrix and fibres are varied, and comparing the rheological results with the proportioning parameters. The importance of an accurate grading curve is also evaluated. The hypothesis is that it is possible to find a correlation between calculated proportioning parameters and resulting rheology that will enable prediction of rheological properties. The results show that the variation in grading curve for the same aggregate is not very relevant to the proportioning parameters. The air content is shown to be of great importance regarding the correlation between matrix volume and packing fraction. Also it is found that it can be possible to predict the air volume based on matrix volume and fiber content.
