Methods for determination of degree of reaction of slag in blended cement pastes

Karen Scrivener, Emmanuel Gallucci, Vanessa Kocaba

To measure the degree of reaction of slag in blended pastes, five methods were studied. Selective dissolution and differential scanning calorimetry are shown to be unreliable, SEM-BSE-IA-mapping is time consuming, but does provide good results with a reaso ...

Mechanisms of degradation of concrete by external sulfate ions under laboratory and field conditions

Aude Chabrelie

The durability of concrete is a major challenge for the construction, which devotes one third to one half of its annual investment to building maintenance. The lack of field data regarding concrete durability, especially in the case of exposure to sulfate ...

Studying the Formation of Ni3C from CO and Metallic Ni at T=265 degrees C in Situ Using Ni K-Edge X-ray Absorption Spectroscopy

Christian Ludwig, Rudolf Paul Wilhelm Jozef Struis, Alexander Wokaun

Metallic Ni nanopowder (Ni-0) was monitored during 23 h of carburization (2CO + 3Ni(0) - Ni3C + CO2, T = 265 degrees C) using Ni K-edge X-ray absorption spectroscopy. X-ray diffraction analysis made afterward at room temperature revealed 28 +/- 3% Ni3C amo ...

Laser micro-spot welding of copper by real-time process monitoring

Simone Amorosi

A new laser micro-spot welding procedure for copper has been developed in order to eliminate the shortcomings of existing techniques based on laser pulse shaping or in-situ temperature control. This procedure consists in dividing the welding process in fou ...
