2.3.2. Flexural Strength

Beams with (100 mm × 100 mm × 500 mm) were utilised to calculate the flexural strength of concrete beams after 7, 14, and 28 days of water curing. Two beam specimens from every mix were assessed on a flexural testing machine with a consistent loading rate of 0.05 kN/s, and the mean value was noted according to (ASTM C 78) [26] (Figure 3).
