Title: Accelerated Concrete Strength Testing by Modified Boiling Method: Concrete Producer’s View
Author(s): R.A. Lapinas
Publication: Special Publication
Appears on pages(s): 75-94
Keywords: accelerated tests; acceptability; compressive strength;
cylinders; quality control; ready-mixed concrete; regression analysis.
Abstract:Accelerated testing of concrete by means of boil-ing test cylinders and testing them at the age of 28 1/2 hours to predict the 28 day strength was used by ready-mixed con-crete producer's quality control laboratory for about two years. Over 300 accelerated tests were carried out indi-cating that 28 day strength can be predicted using this method within the accuracy of +12%. Continuous updating of the accelerated to 28 day strength relationship is neces-sary. The suitability of the method for day-to-day quality control purposes is evaluated.
