I would like to know what experience other engineers have retarding plastic concrete for a continuous deck pour. I have used RX type retarders where the concrete can be confidently retarded to remain plastic for up to 6-8 hours. I have a situation where the concrete needs to remain plastic for up to 14 hours and do not have the luxury of time for R & D. What experience do you have using standard products from Grace, Master Builders, Axiom, etc.? Any experience would be appreciated.
 
I'm not an engineer. YET Take a look at Recover by Grace, and Delvo by Masterbuilders. I have seen both used successfuly in the long term retardation of concrete.
