Table 5 Influence of pumping on fresh properties of the field applied FRC.

Experimental conditions^a	Slump (mm)	Slump flow (mm)	Air content (%)
The first test
Before pumping	130	225/220	4.0
After pumping	170	240/300	3.6
The second test
Before pumping	135	230/240	3.8
After pumping	160	310/280	3.5

^aThe fresh state concrete tests were conducted with the concrete mixture obtained from the randomly chosen agitator trucks: the first and fifth trucks arrived in the field were chosen.
