Effects of aggregate size on alkali-silica-reaction induced expansion

The macroscopic effects of ASR are linked to the damage state at the microstructure level. In this paper we used a combination of experiments and modelling to study the effect of aggregate size on the manifestation of ASR. There are two main ways in which ...

Direct volume variation measurements in fused silica specimens exposed to femtosecond laser

Yves Bellouard

We introduce a new method to investigate localized volume variations resulting from laser exposure. Our method is based on the measurement of fused silica cantilevers deflection from which we calculate the effective stress and density variation in laser-af ...

Effects of uniaxial stress on alkali-silica reaction induced expansion of concrete

Karen Scrivener, Cyrille Dunant

ASR affected concrete in real structures is usually subject to loads which affect the macroscopic expansion of the material. An experimental study was undertaken using sensors embedded in reactive and non-reactive samples loaded on modified creep frames. N ...

Operation and Test Results From the SULTAN Test Facility

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche, Martin Vogel, Stephen Alfred March, Ciro Calzolaio

In the period between August 2010 and August 2011 the SULTAN test facility has been continuously operated, with over one dozen test campaigns. Among the ITER conductors, five Toroidal Field (TF) samples, two Central Solenoid (CS) samples and four NbTi samp ...

Wearout-Aware Compiler-Directed Register Assignment for Embedded Systems

David Atienza Alonso

Although constant technology scaling has resulted in considerable benefits, smaller device dimensions, higher operating temperatures and electric fields have also contributed to faster device aging due to wearout. Not only does this result in the shortenin ...

Exploiting the Divergent Reactivity of Isocyanoacetates: One-Pot Three-Component Synthesis of Functionalized Angular Furoquinolines

Jieping Zhu

A one-pot, three-component synthesis of polysubstituted furo[2,3-c] quinoline 1 was developed based on the new reactivity profile of alpha-(4-nitrophenyl)-alpha-isocyanoacetates. Simply mixing aldehydes 2, ortho-alkynylanilines 3, and alpha-(4-nitrophenyl) ...

Scour formation due to simultaneous circular impinging jet and wall jet

Anton Schleiss

Experiments involving both a circular wall jet and an impinging jet were conducted, as occurring at irrigation control structures or at dams with combined crest and low-level spillways. The effects of the non-dimensional parameters on the scour hole dimens ...

A Laboratory Investigation on Thermal Properties of the Opalinus Claystone

Mohammad Monfared

Some aspects of the thermal behavior of the Opalinus claystone are investigated through laboratory tests conducted on a new hollow cylinder triaxial apparatus specially designed for studying the thermo-hydromechanical behavior of very low permeable materia ...

Influence of the elastic properties of the phases on the coefficient of thermal expansion of a metal matrix composite

Martin Vetterli, Ludger Weber, Reza Tavangar Hamzehkolaei

Copper matrix composites reinforced with low thermal expansion ceramic particles, i.e. SiO2, AIN and diamond, in the range of ceramic volume fractions between 0.55 and 0.85 have been prepared by gas pressure infiltration and are characterized by their coef ...
