Book Description
The report discusses the investigation of membrane-forming compounds for curing concrete which was undertaken for the purpose of developing an acceptance specification, and appropriate test methods for evaluating the suitability of such materials for curing concrete. The report reviews briefly the considerations involved in establishment of the testing procedures, their nature, and some of the precautions that must be observed in their performance. (Author).

Book Description
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. Keywords: Abrasion, Construction materials, Absorptivity, Membrane-forming curing compounds, Moisture retention, Portland cement concrete, Portland cement mortar. (JG).
