We have been told to leave our wall forms in place in hot weather even after the wall is strong enough to strip. It was said they are needed for continued curing of the concrete. This wreaks havoc with our form reuse schedule. Is there any alternative?
Forms do not provide a satisfactory curing enclosure in hot weather. They should be loosened as soon as it is possible to do so without damage to the concrete. Water should then be run onto the exposed top concrete surfaces so that it flows down over the vertical surfaces inside the forms. Curing water should not be much cooler than the concrete. Otherwise it may cause cracking from thermal stresses. Curing should be continued for seven days, or for the time necessary to attain 70 percent of the specified compressive and flexural strength, whichever is less.
