The influence of casting position and disturbance induced by reinforcement on the structural concrete strength

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Rafael Alberto Moccia

It is well known that control specimens used to assess the concrete strength of new structures have different casting and curing conditions than those of actual structures. Notably, after pouring of the concrete and before its hardening, a number of phenom ...

Yielding of a quartz sand from saturated to dry state

Alessio Ferrari

The paper presents the results of an experimental work where we analyse the behaviour of an unsaturated quartz sand in a wide range of degree of saturation (from saturated to dry state). The possibility of anticipating the hydro-mechanical behaviour of the ...

Influence of collars on reduction in scour depth at two piers in a tandem configuration

Anton Schleiss, Giovanni De Cesare, Sargol Memar

Bridge failure, due to local scour at bridge pier foundations, has become a critical issue in river and bridge engineering, which might lead to transportation disruption, loss of lives and economic problems. A practical solution to prevent bridge collapses ...

Basic creep and autogenous shrinkage of Limestone Calcined Clay Cement (LC3)

Julien Ston

The use of supplementary cementitious materials (SCM) to lower the clinker factor of cements is now commonplace, for it benefits performance, economics and ecology. This thesis focuses on ternary blends of limestone and calcined kaolinitic clays, two very ...

Ni-Al2O3 nacre-like composites through hot-pressing of freeze-cast foams

A multi-step process is developed to create a nacre-like ceramic/metal composite. First, a slurry of Ni-coated alumina platelets and NiO nano-particles is directionally freeze-cast and the ice is sublimed, creating a foam with aligned lamellar walls contai ...

Hydro-chemo-mechanical behavior of a sand/bentonite mixture upon wetting paths

Lyesse Laloui, Alessio Ferrari, Donatella Manca

Sand/bentonite (S/B) mixtures are considered as backfilling materials for nuclear waste storage. The paper presents an experimental campaign that was carried out to investigate the swelling behavior of a S/B mixture, under different hydro-chemo-mechanical ...

In-situ strength of individual silicon particles within an aluminium casting alloy

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller

Measurements of local strength are performed in-situ on individual silicon particles that constitute the second phase of aluminium alloy A356. Particles are shaped using Focused Ion Beam (FIB) milling such that, upon the application of a compressive force ...

Autogenous Shrinkage and Creep of Limestone and Calcined Clay Based Binders

Karen Scrivener, Julien Ston, Adrien Jean Régis Maurice Hilaire

This study explored the delayed strains in limestone and calcined clay ternary blends. Autogenous shrinkage measurements are carried out over 2 months and compressive basic creep tests during 28 days after one month of curing. All tests are done using mixe ...

Hydration Study of Limestone Calcined Clay Cement (LC3) Using Various Grades of Calcined Kaolinitic Clays

Karen Scrivener, François Henri Avet

In this study, the influence of the calcined kaolinite content of calcined clay on the hydration of Limestone Calcined Clay Cement (LC3-50) is investigated. It is shown that with the increase of the calcined kaolinite content of the calcined clay, the clin ...

Efficient Decentralized Visual Place Recognition From Full-Image Descriptors

Davide Scaramuzza, Titus Cieslewski

In this paper, we discuss the adaptation of our decentralized place recognition method described in [1] to fullimage descriptors. As we had shown, the key to making a scalable decentralized visual place recognition lies in exploting deterministic key assig ...
