Title: The Effect of Curing Conditions on Compressiv, Tensile and Flexural Strength of Concrete Containing Haydite Aggregate
Author(s): E. B. Hanson, Jr. and W. T. Neelands
Publication: Journal Proceedings
Appears on pages(s): 105-116
Abstract:Lightweight concrete has been given test in the U. S. Maritime Commission's present concrete ship construction program. In its use, problems arose that could not be solved by the application of sand-gravel concrete data. This paper describes some of the strength characteristics of this type of concrete. Data are consistent in showing that rapid moisture loss from Haydite concrete produces a serious retrogression in the tensile and flexural strengths, regardless of the length of curing. This decline in strength, caused by drying shrinkage stresses developing in the outer fibers the moisture content becomes unbalanced, is of temporary nature and apparently can be curbed by the application of paint or membrane seal fol- lowing the moist curing period. The drying shrinkage may well contribute to serious cracking in some types of structures if control is not maintained.
