Appropriate curing is important for concrete to achieve the designed properties. At present, spraying liquid membrane-forming curing compound is the most common method used in pavement and other concrete structure construction. Although a great deal of work has been done on concrete curing, most studies have focused on the effects of curing conditions (such as temperature and relative humidity) on concrete properties (such as strength and freeze/thaw durability). Limited research has been done to study different curing compounds and the changes in the surface concrete properties induced by different curing compounds and applications technologies. The present research was conducted to evaluate curing compounds, application technologies, and their effects on concrete properties, especially on the surface concrete properties. Three curing compounds were selected and applied to concrete (mortars and pastes) at three different times after casting. Two application methods, single and double layer applications, were employed. Moisture content, conductivity, sorptivity, and degree of hydration were measured at different depths in the specimens. Flexural and compressive strength of the specimens were also tested. Statistical analysis was conducted to examine the relationships between these properties. It was found, in this project, that the application of curing compound improved the concrete properties. The application of the high-efficiency-index curing compound gave better properties than the low-efficiency-index curing compound. Compared with other test methods in this project, the sorptivity test was the most sensitive test, which gave difference for different curing conditions.

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.
