FREE FALL OF CONCRETE - TRID

The results of the field studies and practice indicate that free fall of concrete from heights of up to 150 ft (46 m), directly over rebar or at high slumps, does not cause segregation, or reduce compressive strength. Restricting free-fall heights does decrease concrete production rates, increasing owners' without increasing concrete quality.

CONCRETE 101

Slump is a measure of concrete consistency or fluidity. Consistency is the ability of freshly mixed concrete to flow. For given proportions of cement and aggregates (without admixtures), the higher the slump, the wetter the mix. Four-inch (4”) slump is very common with normal weight concrete and is a good average slump for pumping.

But cement is not concrete, so another trial was made, by forming blocks of the latter material 14 inches long, 4 inches wide, and ...
