Title: Attempts To Measure The Cracking Tendency Of Concrete
Author(s): Roy W. Carlson
Publication: Journal Proceedings
Appears on pages(s): 533-538
Abstract:A method is described for determining the resistance to cracking of concrete subjected to drying. A column of concrete is restrained by a centrally-located bar of steel, which is threaded near its ends to provide good bond there while it is coated over its midlength portion to prevent bond. When the concrete dries and shrinks enough to become stressed beyond its tensile strength under the test conditions, an easily visible crack occurs. A few preliminary test results are offered, which in some cases at least, seem to be more nearly in line with field observations than are the results of free shrinkage tests.
