Cold joint vs Construction Joint
Cold joint vs Construction Joint
(OP)
What time lapse between two concrete pours makes the joint in-between a cold joint? Consider 60-80 F temperature, normal weight 3000-4000 psi concrete with standard type 1 cement. The question for SOG as well concrete one metal deck (elevated slab).
I am guessing that ideally one should strive to prepare every cold joint as a construction joint. This way the next pour could be placed almost anytime.

Specific to your question, slabs could be an issue if crack location will be critical or shear capacity is a controlling variable in the design.
