The engineer on our current project did not specify a minimum concrete temperature, the spec says to place concrete in accordance with ACI-301-05.
The answer is an easy one during the prescribed 'cold weather' but if we are not in cold weather concrete (1)is there a minimum temperature...
Is it considered a three bar bundle when a hook from an intersecting wall turns out on the same plane as the horizontal reinforcement at a splice location? Dose this apply to ties and U-bars? Where in ACI is this addressed?
