Further to evaluate the tensile strength, flexural strength test was conducted on specimen of size 100 x 100 x 500 mm. A strength of 4.4 Mpa for NCA concrete and 4.24 Mpa for PCA concrete was observed. Eventhough a slight reduction in strength was noted for PCA as compared with NCA concrete, the values are well within the permissible limits.
