Now, from the fig. 2, it is observed that the split tensile strength was increased up to 10% of fiber content but after that the split tensile strength is not decreased to any percentage of the fiber content. Now for the second case, the observations made on the split tensile strength for 28 days are as follows-
0.21 \(N/mm^{2}\)for 0% of fibers
2.3 \(N/mm^{2}\)for 5% of fibers
1.9 \(N/mm^{2}\) for 7.5% of fibers
2.23 \(N/mm^{2}\)for 10% of fibers
2.1 \(N/mm^{2}\)for 1.5% of fibers content in the concrete.
After the observations were made we conclude that the split strength for controlled mix at 28 days was observed as 0.21 \(N/mm^{2}\)
