Fatigue crack propagation tests under high–low and low–high block loading sequences have been performed in aluminium alloy specimens. The tests were carried out at constant DK conditions. Two stress ratios were analysed: R = 0.05 and R = 0.4. Crack closure was monitored in all tests by the compliance technique using a pin microgauge. The observed transient post load step behaviour is discussed ...

Composite steel–concrete members are adopted in structural applications as a cost-effective and high-speed construction practice. Exploiting the superior corrosion strength-to-weight properties of aluminium, research on composite aluminium-concrete has been reported. Aiming for an even more sustainable durable member, this paper proposes combining aluminium alloys with low carbon geopolymer con...

Unique quantitative bioaccessibility data has been generated, and the influence of surface/material and test media characteristics on the elemental release process were assessed for silicon containing materials in specific synthetic body fluids at certain time periods at a fixed loading. The metal release test protocol, elaborated by the KTH team, has previously been used for classification, ra...
