摘要

A method has been proposed to determine the spacing and width of cracks in polymer modified steel fibre reinforced concrete flexural members. Totally 16 beams of 125 x 200 x 2000 mm were cast and tested. The polymer considered in this study was natural rubber latex. Three different values of percentages of volume fraction of steel fibres (V_g) ie 0.5, 1.0 and 1.5 and three different percentages of dry rubber content (DRC) ie 0.5, 1.0 and 1.5% were used as variables. The computation indicated that the presence of latex and steel fibres influences strain in steel. Hence a correction factor F to that effect was introduced in the proposed method. With the corrected values of steel strains, the maximum width of cracks have been computed and compared with the experimental values obtained in this study. The proposed method for computing the spacing and maximum width of cracks was found to compare satisfactorily with the experimental results.
