*3.3. Flexural Strength Test Results*

To obtain the flexural strength of concrete, three specimens were prepared. According to BS 1881-119:1983 and ASTM C 116-90, the average of the three values was taken as the representative flexural strength. The results of tested specimens are shown in Table 12.
