Curb Construction Curing
As soon as concrete has been placed and finished, it must be cured to develop strength and durability. This important construction operation is essential in achieving the required properties of concrete and it must be carried out on the job site as specified or in accordance with acceptable standard industry practices. Curbs must be protected against loss of moisture, from rain damage, from traffic, and from extreme hot or cold temperatures. ACI 308, Standard Practice for Curing Concrete, is a valuable source of information on taking care of concrete after it has been placed. In normal construction weather, protection can be accomplished by completely covering all exposed surfaces with spray-on membrane curing compound. In extremely dry conditions with high temperature, low humidity and wind, recommendations in ACI 305R, Hot Weather Concreting, should be carefully followed to avoid plastic shrinkage cracking and other ill effects. In cool weather with high humidity, it may not be necessary to use curing compound, but changes in weather should be watched to be sure the concrete is protected adequately. In cold weather, concrete must be kept warm enough to develop its strength and durability, and recommendations in ACI 306R, Cold Weather Concreting, should be carefully followed.
