Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: A search was made for test methods to evaluate the effectiveness of curing concrete. Test methods that include water absorptivity (proposed ASTM test), capillary porosity, combined water, splitting tensile strength, and abrasion resistance were evaluated. Curing compounds having a wide range of water retention values and meeting the requirements of ASTM C 309-89 and CRD-C 300 were obtained for evaluation. A few curing compounds were prepared in the laboratory by diluting one of the CRD-C 300 curing compounds with the vehicle solvent furnished by the manufacturer to obtain curing compounds that would not meet the requirements of either specification. The water-absorptivity test and an abrasion test developed in the laboratory were used to determine the effectiveness of the different curing compounds for curing concrete. Curing compounds meeting the requirements of ASTM-C 309-89 were found to be as effective as curing compounds meeting the requirements of CRD-C 300 for curing concrete. Two of the curing compounds that did not meet the specification requirements were also found to be effective based on the water-absorptivity test method. The abrasion test shows promise as a test method for evaluating the effectiveness of curing and is less time consuming than the water-absorptivity test method.

Available in PDF, EPUB and Kindle. Book excerpt: Excessive early-age concrete surface moisture evaporation causes many problems of concrete pavements, such as plastic shrinkage cracking and delamination; the use of liquid membrane-forming curing compounds is one of the most prevalent methods to mitigate the issues. However, the present standard test, ASTM C 156-98, "Standard Test Method of Water Retention by Concrete Curing Materials" has some inherent limitations in assessing the curing effectiveness of concrete. To better apply curing practices and qualify the curing compound, a new evaluation protocol is introduced in this study. The new protocol consists of using measured relative humidity and temperature to calculate an effectiveness index (EI) which serves as an indicator of the effectiveness of curing. Moistures loss and surface abrasion resistance measurements were made on concrete specimen, and were found to have significant correlation with EI, where higher EI were associated with lower moisture loss and higher surface abrasion resistance. EI was also found to be sensitive to ambient wind condition, types of curing compound and the application rate of the curing compound. Dielectric constant (DC) measurements were also made on concrete specimens indicating the free moisture content on the surface concrete. The DC measurements were also found to differentiate the quality of curing under different ambient conditions, with various types of the curing compounds and the w/c of the concrete mixture. The utility of using the new protocol to assess concrete curing compound effectiveness was also evaluated under the field condition. Both EI and DC measurements showed potentials to distinguish the curing quality for concrete pavement construction.
