3.1. Properties of fresh concrete
The measured values of slump and air content are listed in Table 2 and they fall within the designed rang, i.e., all measured values are 10 ± 2 cm and 4 ± 1% for the slump and air content, respectively. The results of unit weight of concrete change according to the type of used cementitious materials. This is attributed to the difference in the specific gravity of the cementitious materials and air content.
