Abstract

[...]other reports that conclude that the size effect is more important in high-strength concrete should be mentioned [22]. [...]this lack of consensus on the influence of the size effect in fibre-reinforced concrete justifies the need of the present research which analyses the residual strength provided by the reinforcing fibres. [...]the cameras were placed in position and activated on each side of the test configuration. In such a sense, the expected following size effect classical law for concrete occurs: the larger the size, the lower are the strengths obtained. Since the limit of proportionality (fLOP) is controlled by the concrete matrix, not by the fibres, the size effect observed is in accordance with the results of previous published works for plain concrete, such as [32]. Since the limit of proportionality is governed by the concrete matrix, such a result agrees with classical size effect theory for plain concrete In the case of residual strengths, the decoupling of the strengths and the number of fibres placed in the fracture surface allowed the conclusion that the size effect was taking place, detecting the reduction in residual strength in larger specimens with equal number of fibres placed in the fracture surface.
