Title: Microstructural effects in the simulation of creep of concrete

Abstract

The influence of the microstructure on the visco-elastic properties of concrete is investigated using finite element simulations at the meso-scale. Here, we first derive a constitutive law for the creep of the cement paste which accounts for both recoverable and permanent deformations, as well as the influence of temperature and internal relative humidity. The model is calibrated on a set of experiments at the cement paste scale, and then validated after upscaling to the concrete scale. The model is then applied to study the influence of the microstructure on the macroscopic creep of concrete. We show that materials with finer particles exhibit less creep, and that the anisotropy of creep can be explained with the shape and orientation of the aggregates. Furthermore, the acceleration of the stress relaxation in the presence of damage is explained by the micro-mechanical interaction between the aggregates, the cement paste, and the micro-cracks.

Microstructural effects in the simulation of creep of concrete

Journal Article Giorla, Alain B., E-mail: giorlaab@ornl.gov ; Dunant, Cyrille F., E-mail: cfd30@cam.ac.uk - Cement and Concrete Research

The influence of the microstructure on the visco-elastic properties of concrete is investigated using finite element simulations at the meso-scale. We first derive a constitutive law for the creep of the cement paste which accounts for both recoverable and permanent deformations, as well as the influence of temperature and internal relative humidity. The model is calibrated on a set of experiments at the cement paste scale, and then validated after upscaling to the concrete scale. The model is then applied to study the influence of the microstructure on the macroscopic creep of concrete. We show that materials with finer particlesmore »« less

Simulation of the effect of geometrical changes of the microstructure on the deformational behavior of hardening concrete

Journal Article Lokhorst, S J ; Breugel, K van - Cement and Concrete Research

A constitutive model for hardening concrete is presented, in which the evolution of the microstructure is accounted for explicitly. The concrete is divided into structural components made of anhydrous cement, cement gel, and aggregate with nonchanging elastic and time-dependent stress/strain relations. The division of the microstructure into different structural components and the stiffening of the microstructure by the addition of new components enables the simulation of a deformational behavior that is highly influenced by the course of the hydration process. In this manner, the creep of concrete on the macro level is described as a joint behavior of elastic andmore »« less

NEUTRON-IRRADIATION–INDUCED DAMAGE ASSESSMENT IN CONCRETE USING COMBINED PHASE CHARACTERIZATION AND NONLINEAR FAST FOURIER TRANSFORM SIMULATION

Conference Le Pape, Yann ; Tajuelo Rodriguez, Elena ; Arregui Mena, Jose' ; ...

Understanding irradiation effects in concrete cavities of light water reactors is critical to the long-term operation (60+ years) of US nuclear power plants. Susceptibility of concrete to neutron irradiation greatly varies as a function of its constituents: coarse aggregates, sand, and hardened cement paste (hcp). In particular, higher irradiation–susceptibility of aggregates was found to be a direct function of radiation-induced volumetric expansion (RIVE), or the propensity of aggregates to swell as a function of mineral contents, structures and textures. Irradiation-induced amorphization is accompanied by significant swelling, especially in silicates. For example, the maximum volumetric expansions of quartz and feldspars havemore »« less

Experimentally Validated Computational Modeling of Creep and Creep-Cracking for Nuclear Concrete Structures

Technical Report Grasley, Zachary

In a Nuclear Power Plant, one of the most important components is the concrete nuclear reactor cavity, which serves both a structural and protective function as the biological radiation shield. Given that creep has been identified as a major knowledge gap in the assessment of nuclear structures (NUREG/CR-7153), this work helps to further the understanding of creep behavior of massive concrete containment structures for decades to enable safe and long-term operation of these facilities. This project has developed a robust, experimentally validated model to predict creep in nuclear concrete structures for up 60 years using short-term creep data thereby enablingmore »« less

An integrated multiscale experimental-numerical analysis on reconsolidation of salt-clay mixture for disposal of heat-generating waste. Final report

Technical Report Sun, WaiChing

The possibility of permanent disposal of nuclear waste in salt has been investigated for decades. This interest is primarily due to the availability of the stable salt formations and the desirable thermal-hydro-mechanical behaviors of salt (e.g. high thermal conductivity, low permeability, self-healing). To ensure the long-term safety of the disposal, sealing is one of the primary concerns \citep{hansen2011salt}. One promising approach is to reconsolidating the crushed salt readily available in the repository with clay (Bentonite) additive \citep{hansen2015salt}. This treatment is favorable, because clay exhibits low permeability and sorbs radionuclides and water during the early stage of the repository \citep{hansen2011salt}. Whilemore »« less
