Additively manufactured steel reinforcement for small scale reinforced concrete modeling: Tensile and bond behavior

Small scale (1:30-1:40) Reinforced Concrete is useful for centrifuge testing. However, manufacturing the reinforcing cages by hand at this scale is practically difficult. This paper suggests that small scale reinforcement can be manufactured using a metal ...

Enhanced Room-Temperature Photoluminescence Quantum Yield in Morphology Controlled J-Aggregates

Frank Nüesch, Jakob Heier, Surendra Babu Anantharaman

Supramolecular assemblies from organic dyes forming J-aggregates are known to exhibit narrowband photoluminescence with full-width at half maximum of approximate to 9 nm (260 cm(-1)). Applications of these high color purity emitters, however, are hampered ...

The reaction between metakaolin and limestone and its effect in porosity refinement and mechanical properties

Karen Scrivener, Franco Alberto Zunino Sommariva

n limestone calcined clay cements (LC3), more hemicarboaluminate and monocarboaluminate is observed, as compared to other blended cements, from the reaction of metakaolin with limestone. In this study, it is shown that the formation of these carboaluminate ...

Modeling the kinetics of the main peak and later age of alite hydration

Alexandre Reda Constantin William Caleb Ouzia

The aim of this thesis is to understand the mechanisms underlying the main hydration peak and later ages of alite hydration; it proposes new mechanistic models for these two stages. Alite is the main constituent of Portland Cement (PC), and is responsible ...

The needle model: A new model for the main hydration peak of alite

Karen Scrivener, Alexandre Reda Constantin William Caleb Ouzia

This article presents a new model for the main hydration peaks of tricalcium silicate and alite on the assumption that C-S-H nucleates and grows as needles. The model relies only on directly observable quantities and reproduces the transition from the acce ...

The reuse of load-bearing components

Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting, Catherine Elvire L. De Wolf

Load-bearing systems of buildings are poorly valued when they reach functional obsolescence. Still, they contribute the most to the material weight and embodied impacts of buildings and infrastructures. The reuse of structural components therefore offers g ...

The influence of the filler effect on the sulfate requirement of blended cements

Karen Scrivener, Franco Alberto Zunino Sommariva

In some blended cements, the optimum amount of sulfate addition differs from that observed in OPC. This study aims to understand the mechanism behind the impact of two SCMs, namely metakaolin and limestone, on the sulfate balance of blended cements. No sig ...

Next generation UHPFRC for sustainable structural applications

Emmanuel Denarié, Amir Hajiesmaeili

Over the last few decades, ever-increasing demands of society to the built environment have continually increased consumption of energy and materials for the construction and maintenance of structures. Meanwhile, Strain Hardening Ultra High-Performance Fib ...
