Title: Progress In Determining the Relation Between Test Cylinders and Concrete in the Structure
Author(s): Harlan H. Edwards
Publication: Journal Proceedings
Appears on pages(s): 57-64
Abstract:Tests on four college structures in Claremont, Calif., indicate that welldesigned, placed, and cured con-crete has strength higher than standard test cylinders, due to lowering of W/C by form absorption and per-colation. Cylinders cast in unwaxed paper molds surrounded by wall concrete in curing, prove reliable indicators of concrete characteristics. Damp sand job-curing of cylinders is worthless. Slab concrete is generally of higher strength than walls of the same mix.
