Never heard of the 8' free fall rule however I have never heard of someone trying to do that.. You would need goggles with windshield wipers!!
On another note, I poured 2 identical walls for my shop: 40' x 4' x 2', 5000lb. One was poured at about 40 degrees with no calcium and the temperature dropped to I think about 10 degrees f.
The second wall was poured with hot water and calcium and both walls have 5/8 rerod cages and snap-tie forms were used.
Both walls are 20 years old with virtually no cracking.
The odd part is that the wall poured with the hot water and calcium rings when you hit it with a hammer while the other one gives the usual dull thud.
Just curious if you knew why.
Regards, Brad
Also the weather has broken here (finally) and I will be trying my hand at laying block soon. Will post the antics for the enjoyment of all.
