The Pickett effect at early age and experiment separating its mechanisms in tension
Abstract A new experimental approach that allows separation of the components of the Pickett effect due to surface microcracking and stress-induced shrinkage is developed and demonstrated for early age concrete subjected to tensile loads induced in restrained shrinkage tests. The experiment measures creep of three concree materials subjected to same loads, but under different environments: moist-cover, sealed, and drying conditions. The key features of the experiment are the suppression of shrinkage in the moist-cover test, and the uniform internal drying in the sealed test. The results confirm that the Pickett effect in tension has two sources: stress-induced shrinkage and microcracking. The new approach provides insght to creep, shrinkage, softening, and cracking behaviour under tensile load, and explains behavioral differences between plain and fiber reinforced concrete.
