This paper presents a novel rheological thixotropy model that specifically appertains to the
characterisation of materials that are suitable for 3D printing of concrete (3DPC). The model …

The behaviour of fresh and hardened alkali-activated slag (AAS) and OPC concretes was
compared and the effect of mixing time assessed. OPC and AAS concrete slump and …

Concrete is the largest volume material used by man and is irreplaceable for innumerable
large infrastructure developments. From the point of view of natural resources, ecology and …

The interest in the elastic and yielding properties of fresh cement-based materials has
recently grown due to the development of new processing techniques, which avoid the use …
