Prediction of creep of polymer concrete

Journal of Applied Polymer Science, 1999
Polymer concrete possesses viscoelastic properties conditioned by relaxation processes in the polymer binder. Their acceleration with an increase of temperature (principle of time–temperature equivalence) is used in predicting the long-term creep of polymer concrete. Physical aging of the polymer binder influences the creep of polymer concrete.

Prediction of creep of polymer concrete

Mechanics of Composite Materials, 1995
We studied the applicability of the phenomenological approach to the prediction of long-time creep of polymer concrete consisting of polyester binder with diabase filler and diabase aggregate. We discovered that the principles of temperature-time analogy, of moisture-time analogy, and of temperature-moisture-time analogy are applicable to the ...

Creep of Concrete in Bridge Standards

CONCREEP 10, 2015
As structural concrete is a continuously-developing material, evolution in the estimation of its material properties can be seen with the development of concrete technology. The paper reviews methods for predicting concrete creep in bridge structures. The principal variables that influence creep are outlined.

Creep of a silica fume concrete

Cement and Concrete Research, 1985
Abstract Creep tests have been performed on a concrete composition where part of the cement (25%) was replaced by a silica fume. The results show that the total deformation is decreased in drying condition, without any significant reduction of the basic creep.

Creep of concrete: From measurement of mechanics

1977
The lecture on creep of concrete considers the development of relationship between creep and the variables, age, time under load, stress and temperature. The relationships are founded on experimental data, and a description is given of the modifications needed to adapt them for use in constitutive equations of engineering mechanics.

Modelling of Creep in High Strength Concrete

Creep is the time dependent deformation of concrete induced by sustained stress. Several different prediction models are currently used throughout the world, however little is known about their ability to predict creep in high strength concretes. Several of these models were designed to be used on normal strength concretes.

Uncertainty and models for creep of concrete

Cement and Concrete Research, 1983
Abstract An engineer involved in practical design must often choose between using approximate rules of thumb, and more rigorous analyses. The problem may be tackled using decision theory. An important element in this analysis is the estimation of probabilities of future values of creep.

Creep Recovery of Plain Concrete

ACI Journal Proceedings, 1968
RESULTS OF STUDIES PERFORMED ON ONE HUNDRED, 1100 DAY OLD, PLAIN CONCRETE PRISMS ARE PRESENTED. THESE PRISMS HAD BEEN PLACED UNDER SUSTAINED LOAD AT 28 DAYS. CREEP RECOVERY BEHAVIOR, UPON UNLOADING, IS EXAMINED. A NUMBER OF PRISMS WERE UNLOADED AND IMMEDIATELY RELOADED TO DETERMINE THE EFFECT OF THIS LOAD CYCLE ON CREEP.

Creep of Concrete — A Stochastic Quantity

1982
The magnitude of creep is regarded as a stochastic quantity, because of random variations of important influential factors. A test-program on a statistical basis has been carried out to investigate the influence of actual variations of the concrete composition (wcr;acr), on creep.
