Abstract:
Properties and proportions of mix constituents, age of concrete at loading, storage conditions, stress-strength ratio, and other factors affecting creep are discussed. Various expressions for the creep-time relation are discussed, and prediction curves for creep of concrete of different properties and stored under different condition are presented.

A hypothesis for creep is presented in terms of the microstructure and properties of hydrated cement. An experimental investigation, designed to provide a quantitative basis for the hypothesis, is briefly described. Procedures are presented for estimating creep in terms of the volumetric composition of the concrete, the degree of hydration, and the observed free shrinkage characteristics.

The influence of amount of torque, duration of loading, age on loading, humidity conditions, and sand content on various deformation components was studied. A theory, formulated on the reversible and nonreversible time-processes taking place in the mortar, is presented that attributes shrinkage, swelling, and creep and its recovery to water migration within the cement gel.

Creep and long-time creep-recovery tests were conducted on four different concrete mixes. Time.dependent deformations were measured during loading and unloading for a 3 year test period. A rheological model, representing the creep and creep-recovery of the concrete, is proposed and the model constants evaluated.

Boris Bresler and Lawrence Selna
The influence of environment on time-dependent behavior of reinforced concrete structures is introduced and the principal variables discusssed. Deformation due to variable stress history is described in general terms. A simplification in determining specific creep function is explored. Methods for analysis of stresses and deformation which account for time- and environment- dependent processes are outlined.
