Research output:
The concrete slump test—A rheometer by definition?
(Construction and Building Materials, February 2025)
““This work demonstrates that by incorporating digital tools such as 3D reconstruction and accelerometers, the slump test can provide accurate measurements of yield stress and viscosity in practical settings.””
Yield stress prediction from 3D reconstruction of fresh concrete slump
(Cement and Concrete Research, December 2023)
“This paper proposes a novel method to predict yield stress from slump by directly measuring the height of the unyielded region, via a 3D reconstruction approach. The results of this study suggest that, for the first time, a valuable fundamental rheological property can be confidently derived from a standard concrete slump test.”
Digital threads for sustainable concrete: A prototype traceability system
(Structural Concrete, June 2024)
“This work advances knowledge of the appropriate traceable resource units and critical tracking events within concrete practice, develops effective marking procedures and forms a prototype constituent-to-product traceability system.”
Bridging the information gap using targeted digital transformation: process mapping large-scale concrete activity
(Building Research and Information, August 2024)
“This study develops a process flow model for the concrete sector. The information requirements and actions of all stakeholders in the system are collectively mapped for the first time. Tthe developed process understanding aids in targeted digital transformation to tackle the information gap in practice.”
Shear Strengthened Reinforced Concrete.
Understanding the size effect in beams strengthened with fibre reinforced polymer bars utilising the deep embedment method. This involved the scale construction and testing of reinforced concrete specimens.
