This study investigates the engineering performance and CO₂ footprint of mortar mixers by replacing Portland cement with 10%, 20%, 40% and 60% fly ash, a common industrial waste material. Samples of self-compacting mortar (SCM) were prepared with four different water/binder ratios and varying dosages of superplasticizer to give three ranges of workability, i.e., normal, high and self-compacting...

Self-consolidating concrete (SCC) mixtures designated for precast, prestressed applications should be highly workable to flow easily through restricted spacing and completely encapsulate reinforcements without any mechanical vibration. Key workability characteristics of SCC can be described in terms of filling ability, passing ability, and resistance to segregation. These properties are typical...

Editorial Consolidating Strengths I remember receiving a wonderful message from Cambridge University Press around three years ago – an invitation to take over as Editor of Medical History. I accepted almost instantaneously, but remember being nervous about the task at hand. At least as nervous as I had been whilst walking into a cage containing around fifty teenaged lions and lionesses with a g...
