Adsorption of superplasticizer admixtures on alkali-activated slag pastes

Paul Bowen, Yves Houst

Alkali-activatedslag(AAS) binders are obtained by a manufacturing process less energy-intensive than ordinary Portland cement (OPC) and involves lower greenhouse gasses emission. These alkaline cements allow the production of high mechanical strength and d ...

The temperature is known to influence the strength and durability of concrete. Temperature has also a great influence on the creep of cementitious materials. Previous investigations have not provided a complete understanding of these effects; in particular ...

In this article we shall describe our quest and ultimate success in furthering our understanding of the action of superplasticizers on the rheology of cement and concrete. By specifically producing superplasticizers with varied architectures, we have been ...

Deterioration of cementitious materials by sulfate ions is a concern for concrete in contact with ground water (and in a lesser extent sea water) in many parts of Europe, and is an important issue for underground construction identified as a major area for ...

Sulfate attack and the role of internal carbonate on the formation of thaumasite

Thomas Schmidt

The sulfate attack is known to influence the durability of concrete. In general, significant damage due to sulfate interaction results in the structural breakdown of the concrete structure. However, the precipitation of thaumasite due to sulfate concentrat ...

The role of cement in improving concrete durability is complex. Generally the role played by cement is secondary to the role of concrete mix design and curing. Some of these interacting effects are illustrated by discussing the roles of calcium hydroxide, ...

Superplasticizers (SP) of the “new generation” are essentially polycarboxylate polymers. Polymers of this family can be produced with almost infinite variations in their chemical structure, which allow the fulfilment of specific (tailored) properties. Thes ...

2005

During the last 20 years, backscattered electron imaging of polished surfaces has become well established as a method for the study of cement and concrete microstructures. The technique has many advantages, including the visualisation of representative cro ...

This paper describes the so called interfacial transition zone - ITZ - in concrete. This is the region of the cement paste around the aggregate particles, which is perturbed by the presence of the aggregate. Its origin lies in the packing of the cement gra ...
