Creep and creep recovery properties of polystyrene aggregate concrete

Construction and Building Materials, 2014
Abstract The present study aims to characterize the creep behaviour of Polystyrene Aggregate Concrete (PAC). The creep and creep recovery of PAC were determined experimentally and compared with normal weight concrete. The parameters studied include polystyrene aggregate (PA) content, curing and storage conditions.

A model for the creep of concrete

Cement and Concrete Research, 1975
Abstract Porosity and density changes were measured for a series of mortar specimens and a series of cement paste specimens subjected to various compressive stress histories during desorption and sorption cycles. It was found that hydration is inhibited by compressive stress.

Creep of lightweight concrete

Magazine of Concrete Research, 1959
Summary Creep data covering periods of up to 18 months for concretes made with expanded-shale aggregates and having compressive strengths of 3,000 and 5,000 lb/in2 at 28 days are reported. These are compared with data for sand-gravel concretes of comparable strength.

The mechanism of creep in concrete

Matériaux et Constructions, 1968
AN ATTEMPT IS DESCRIBED TO FIND THE BASIC PHYSICAL FACTORS DETERMINING CREEP IN CEMENT PASTE, AND SELECT AMONG THE EXISTING THEORIES ON CREEP THE CORRECT ONE BY EXPERIMENTAL INVESTIGATIONS. CEMENT PASTE AND CONCRETE SAMPLES WERE DRIED, LOADED, AND RESATURATED AT VARIOUS TEMPERATURES.

Creep of concrete-filled steel tube considering creep-recovery of the concrete core

Advances in Structural Engineering, 2019
Concrete creep results in the strain increment of concrete-filled steel tube. In this article, a new method was established for creep prediction of concrete-filled steel tube considering the creep-recovery effect of the concrete core with creep model and separate creep-recovery model, named two-function method.

The shrinkage and creep of concrete

Magazine of Concrete Research, 1959
Summary This paper describes an investigation made at the Laboratoires du Bâtiment et des Travaux Publics at Paris into the principal factors influencing the creep and shrinkage of concrete. The main conclusions drawn are that both creep and shrinkage are directly proportional to the amount of cement paste in the concrete, that creep is directly ...

Creep and shrinkage of concrete

Matériaux et Constructions, 1969
The paper gives a short description of the different types of test series on creep and shrinkage of concrete, which are under work at the Cement and Concrete Research Institute at the Technical University of Norway. Some results are given concerning creep and shrinkage of concrete under periodic changes in moisture content.

Recovery of creep and observations on the mechanism of creep of concrete

Applied Scientific Research, 1960
Test data on the recovery of creep of mortar specimens made with different cements are presented. It is shown that, whereas creep depends on the strength of mortar (as influenced by the cement), the creep recovery is not a function of this strength. From measurements on the change in weight of specimens, under load and free-standing, it is concluded ...

Basic and drying creep of concrete

Matériaux et Constructions, 1969
From considerations of the gel compliance factor and of a creep parameter P, involving the volume concentrations of gel and of cement paste, and using a hyperbolic creep-time expression, an expression for creep of the type of Eq. (13) has been derived.
