Clay calcination technology: state-of-the-art review by the RILEM TC 282-CCL

Karen Scrivener, Franco Alberto Zunino Sommariva, Alastair Thomas Matthew Marsh, Mohsen Ben Haha, François Henri Avet, Shashank Bishnoi, Adrian Alujas Diaz, Anuj Parashar

The use of calcined clays as supplementary cementitious materials provides the opportunity to significantly reduce the cement industry's carbon burden; however, use at a global scale requires a deep understanding of the extraction and processing of the cla ...

Towards tailored cement-based materials with ground calcium carbonates

Emmanuel Denarié, Lionel Sofia

Proportioning the dosage of Ground Calcium Carbonates (GCC) in cementitious materials, beyond current normative levels, is one of the most promising ways towards sustainability of mortar and concrete technology. Performance parameters such as the water/bin ...

This paper investigates the phenomenon of cover spalling in reinforced concrete induced by bond or by the action of an inner pressure. This research is based on an experimental programme comprising a series of bond tests and a series of tests with inner-pr ...

By studying approximately a century of cement and concrete in Switzerland, this project examines the relations between institutions, discourse, and technology as they intersect in the material. The project is framed so that the establishment of organizatio ...

The reduction of green-house gas emissions is one of the global challenges that our society is facing and the production of cement plays a major role because concrete is the most used material worldwide. For every 1000 kg of cement produced, 900 kg of CO2, ...

Blended cements, where Portland cement clinker is partially replaced by supplementary cementitious materials (SCMs), provide the most feasible route for reducing carbon dioxide emissions associated with concrete production. However, lowering the clinker co ...

Treatment by accelerated carbonation has been widely studied to enhance the quality of recycled concrete aggregates (RCA) and hence the performance of new concrete produced with the RCA. This is often ascribed to the densification of RCA. This study invest ...

The use of cement and concrete, among the most widely used man-made materials, is under scrutiny. Owing to their large-scale use, production of cement and concrete results in substantial emission of greenhouse gases and places strain on the availability of ...

2020

The article links two seemingly different fundamental theoretical concepts of autopoiesis and homeostasis and tries to apply them to the realm of socio-technical systems with the use of the Fractal Enterprise Model (FEM). Autopoiesis is the property of a s ...

Prediction of autogenous shrinkage of cement pastes as poro-visco-elastic deformation

Karen Scrivener, Zhangli Hu, Pietro Lura

Precise and robust predictions of autogenous shrinkage of high performance concrete are essential to limit self-induced stresses and cracking in modern concrete structures. This paper presents predictions of autogenous shrinkage for three cement pastes of ...
