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.

Concrete creep mechanism explained
C&EN Global Enterprise, 2016Concrete is ubiquitous as a building material, but it suffers from “creep,” long-term deformations caused by its own weight, that damage its integrity and make it susceptible to cracking and crumbling. Now, scientists have evidence this creeping phenomenon stems from nanoscale dissolving of concrete’s primary phase, calcium silicate hydrate (CSH ...

Creep of air-entrained concrete
Magazine of Concrete Research, 1969Synopsis The creep of mixes having the same workability and strength at loading is shown not to be affected by the presence or absence of entrained air, so that the approximate linear relationship between creep and stress/strength ratio previously foundfor plain concrete applies also to air-entrained concrete. A correlation between specific creep and

Applied Mechanics and Materials, 2015
The consideration is given to a specific component of the creep of concrete which becomes apparent within one day from the moment of load application, the so called “short-term creep”. Since the entire creep of concrete is conditioned by its water content, the short-time creep must be assigned to the most mobile water – capillary water.

Creep Buckling of Concrete Shells
1988Essential features of the extension of an existing computer program for ultimate load analysis of reinforced concrete structures to allow consideration of long-time deformations are described. The program is applied to recompute experiments, reported in the literature, concerning creep buckling of shell models of the form of spherical caps cast of ...

Creep and shrinkage of concrete
Matériaux et Constructions, 1969The 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.

Creep Recovery of Plain Concrete
ACI Journal Proceedings, 1968RESULTS 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 and creep recovery properties of polystyrene aggregate concrete
Construction and Building Materials, 2014Abstract 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.

Creep of roller-compacted concrete
Hydrotechnical Construction, 19911. Rollcrete has creep, the general regularity of the development of which in time and as a function of the age of the concrete can be described by the formula proposed earlier by Aleksandrovskii and widely used for ordinary concrete. 2.

Creep of concrete: From measurement of mechanics
1977The 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.
