\curing concrete with Curing compounds
(OP)
I have a contractor who wants to use curing compounds instead of water to cure concrete, I have not used these compounds before and know nothing about them, my qustion is:
1- do these compounds totaly replace water, or are they used togethr with water
2- are they applied for 7 days like water , or once only and the work continues? if so how can you tell that the concrete has reached its strength
3- are they effective
thanks

RE: \curing concrete with Curing compounds
To get back to your questions, I believe they eliminate the need to wet cure (not positive about this), they are applied once and your done, and, depending on the variety being used, I believe them to be very effective. The strength of the concrete is still measured in the typical fashion. The idea being that the design mix is intact since nothing can get in or out through the curing compound barrier, so cylinders should be accurate.

Typically they are spray applied once. There can be issues if sealers or coatings are to be applied afterwords.
My main issue with curing compounds is the application. Time and time again the concrete gets a quick spray and the contractor is done. I was onsite for a demonstration by a sealer manufacturer. The stipulated coverage rate meant a heavy spray in each direction, something I had never seen applied onsite before. The effectiveness of the sealer decreases rapidly if the coverage rate is not met.
