Influence of Shrinkage-Reducing Admixtures on Moisture Absorption in Cementitious Materials at Early Ages

The water-absorption behavior of cement pastes (w/c=0.30) containing varying concentrations (i.e., 0, 0.2, and 5%) of a shrinkage-reducing admixture (SRA) was measured. Moisture ingress was monitored using X-ray absorption. A decrease in both the depth of ...

Simulation of volume changes of cement paste at early age

Karen Scrivener, Amor Guidoum, Ines Jaouadi

The evolution of early age mechanical properties and volume change of cement paste is performed through Finite Element analysis on a 3D computer-generated cement paste. The time evolution of the hydrating microstructure is generated by μic(mike), a vectori ...

Quantitative microstructural characterisation of cement paste submitted to different moderate temperature and loading conditions

Karen Scrivener, Emmanuel Gallucci

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 ...

ARCHE D06 - Recommendations for the tailoring of UHPFRC recipes for rehabilitation

Emmanuel Denarié

The extremely low permeability of Ultra High Performance Fibre Reinforced Concretes (UHPFRC) associated to their outstanding mechanical properties make them especially suitable to locally "harden" reinforced concrete structures in critical zones subjected ...

Importance of microstructural understanding for durable and sustainable concrete

Karen Scrivener

This paper presents the importance of microstructural studies for understanding concrete durability. Three examples-sulfate attack; alkali silica reaction and bacteriogenic corrosion in sewers arc used to illustrate the pitfalls which can arise from conven ...

Étude numérique et expérimentale du retrait endogène de la pâte de ciment au jeune âge

Ines Jaouadi

Autogenous shrinkage is a complex phenomenon in which many physical and mechanical mechanisms are involved. The latter may also interact between each other and many of these coupling mechanisms are still not well understood. Understanding of these mechanis ...

Design and Function of Novel Superplasticizers for More Durable High Performance Concrete (Superplast Project)

Paul Bowen, Yves Houst, François Perche

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 ...

Durability Of Field Concrete Made Of Portland Cement And Supplementary Cementitious Materials Under Several European Exposure Conditions

Karen Scrivener, Emmanuel Gallucci, Aude Chabrelie

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 ...

Simplified concrete resistivity and rapid chloride permeability test method

A simplified method of measuring concrete resistivity, as an index of permeability, has been developed that is similar to ASTM C1202 or the rapid chloride permeability test (RCPT). It is significantly faster and easier to perform, however In this test, cyl ...
