Curing is one of those activities that every civil engineer and construction worker has heard of, but in reality does not worry about much. In practice, curing is often low on the list of priorities on the construction site, particularly when budgets and timelines are under pressure. Yet the increasing demands being placed on concrete mixtures also mean that they are less forgiving than in the past. Therefore, any activity that will help improve hydration and so performance, while reducing the risk of cracking, is becoming more important. Curing Concrete explains exactly why curing is so important and shows you how to best do it. The book covers: The fundamentals behind hydration How curing affects the properties of concrete, improving its long-term performance What curing technologies and techniques you can use for different applications How to effectively specify, provide, and measure curing in a project The author also gives numerous examples of how curing—or a lack of it—has affected concrete performance in real-world situations. These include examples from hot and cold climates, as well as examples related to high-performance concrete, performance parameters, and specifications and testing. Written for construction professionals who want to ensure the quality and longevity of their concrete structures, this book demonstrates that curing is well worth the effort and cost.

SOME OF THE METHODS OF CONCRETE CURING USED IN NEBRASKA WERE EVALUATED. SEVEN CURING METHODS WERE USED, WHICH INCLUDED WATERPROOF PAPER, PLASTIC FILM, WHITE PIGMENTED CURING COMPOUND, WET BURLAP, CLEAR CURING COMPOUND, OR COMBINATIONS OF THESE. THREE 700-FOOT SECTIONS OF CONCRETE PAVEMENT WERE CURED BY EACH METHOD. THE PROJECT WAS CONSTRUCTED DURING COOL, HIGH-HUMIDITY WEATHER - NEAR IDEAL FOR CONCRETE CURING. THE EFFECT OF EACH TYPE OF CURING WAS DETERMINED BY LABORATORY TESTS ON CORES FROM THE PAVEMENT AND BY PAVEMENT CONDITION SURVEYS. THE LABORATORY TESTS ON THE CORES INCLUDED ABRASION TEST, AIR VOID TEST, MIXING WATER TEST, AND STRENGTH TEST. NONE OF THE TESTS SHOWED ANY VARIATION WHICH COULD BE ATTRIBUTED TO CURING METHOD. THE FIELD INSPECTION ALSO SHOWED NO SIGNS OF SURFACE DETERIORATION WHICH COULD BE ATTRIBUTED TO CURING. BECAUSE OF THE COOL, HUMID WEATHER CONDITIONS DURING CONSTRUCTION, LITTLE OR NO DIFFERENCES DUE TO THE CURING MEDIA COULD BE DETECTED.

Eleven compounds designated as colorless and two designated as water-based were evaluated to their suitability for curing of concrete and for their lack of color. All met present requirements for sprayability, drying time, and flash point. Only ten met the moisture- retention requirements. The three that failed the moisture test were one styrene- acrylate resin and both water-based compounds. Infrared analysis revealed that the colorless materials compounds. Infrared analysis revealed that the colorless materials represent 5 different chemical classes: 4 chlorinated rubbers; 2 modified styrene-butadienes; 1 phthalic alkyd; 3 carboxylated hydrocarbons; and 1 styrene- acrylate. Both water-based materials were identified as sodium silicate liquids. Infrared measurements were used to detect chemical and physical changes of the colorless materials when exposed to laboratory conditions and natural sunlight. (Author, modified-PL).
