WebThe first crack strength is generally proportional to the amount of fibre in the mix and the concrete mix design. Two theories have been proposed to explain the strengthening mechanism. The first proposes that as the spacing between individual fibres become closer, the fibres are better able to arrest the propagation of micro cracks in the matrix.
