True, but I am pouring a base for 120 feet of AB-105 and three guy
anchor points...more like 7.5 yards total.
The plans filed with the building dept. call for 4000 PSI. The 5000
rating is just insurance. I figured if it takes longer than I had
hoped to pump the concrete 300 feet into 4 different holes, I won't
be compromising strength if I have to add a little water to add
workability time. All I need is to clog up a $100,000 concrete
