The effect of the length of macro synthetic fibres on ...

Nowadays macro synthetic fibres are able to compete with steel fibres despite their low Youngs Modulus. This is due to their different pull-out mechanism and a larger number of individual fibres per kilo compared to steel fibres. Macro synthetic fibres bond to the concrete along their full length, usually with an embossed surface, while steel fibres are mostly anchored by their hooked ends.

Nov 20, 2019  From the point of view of the different processes, the fitting effect of “A-P vs B-P” was the best, with the average of R 2 reaching up to 0.9207, whereas the worst was the entire process of “A-S vs B-P” owing to the superimposed effect of errors from both the pumping and spraying processes. Thus, the property prediction after pumping ...
