Carbonation Rate of Alkali-Activated Concretes: Effects of Compositional Parameters and Carbonation Conditions

The current ability to predict the carbonation resistance of alkali-activated materials (AAMs) is incomplete, partly because of widely varying AAM chemistries and variable testing conditions. To identify general correlations between mix design parameters and the carbonation rate of AAMs, RILEM TC 281-CCC Working Group 6 compiled and analysed...

Long-Term Mechanical and Durability Behaviour of Two Alkali-Activated Types of Concrete

A promising solution for reducing the carbon footprint of concrete is the use of alkali-activated concretes (AAC). Before this material can be widely applied, its long-term behaviour needs to be understood, especially since some studies reported a decrease of mechanical properties over time. Similarly, Prinsse et al. reported decreasing...

Fracture and Failure of Adhesives

This article presents an overview of methods for analyzing the facture and failure of adhesives. Special attention is given to stress analysis in adhesive bonds, as the difficulty of performing an accurate stress analysis is a major limitation of many failure analysis methods. The article also covers the effect of manufacturing and...

Chloride Ion Penetration into Cracked UHPFRC During Wetting-drying Cycles

The subject of this paper is the extent to which, during wetting–drying cycles, chloride ions can penetrate Ultra-high-Performance Fibre Reinforced Cementitious Composites (UHPFRC) specimens subjected to combined mechanical and environmental load. Pre-cracking was obtained by subjecting prismatic specimens (40 × 40 × 60mm³) to four...
