Document: 

SP9-01

Date: 

January 1, 1964

Author(s):

Adam M. Neville and Bernard L. Meyers

Publication:

Symposium Papers

Volume:

9

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.

Abstract:

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.

Date:

Symposium Papers

Volume:

Abstract:

Develops a procedure for including the effects of creep and shrinkage in design and analysis. The objective of the procedure is to permit the designer to automatically satisfy deflection criteria as well as allowable working stresses. Working equations for the general case are developed and equations are given for special cases, including beams with and without compressive reinforcement, and prestressed concrete beams.

Author(s):

Publication:

Symposium Papers

Volume:

9

Abstract:

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.
