Fields of expertise

Quantitative microstuctural characterisation Microstructural modelling

Mission

Research activities at the Laboratory of Construction Materials (LMC) are focused on cementitious materials and on the micro-mechanics and processing of wood.The complexity and heterogeneity of cementitious materials make difficult the establishment of microstructure-property relationships. Within the LMC, quantitative microstructural characterisation and microstructural modelling provide a unique capability to study, understand and improve cementitious materials and their applications, ranging from mixing and placing to long-term performance (durability). Two principal techniques are used : Scanning Electron Microscopy (SEM) and X-ray Diffraction coupled with Rietveld type analysis to quantify the development of crystalline hydration products (and by difference amorphous products). These techniques are complemented by the use of other classic and new techniques (e.g. TEM, TGA, NMR) available within EPFL or through international collaborations.The LMC studies also special cementitious materials which respond to severe environments thanks to properties such as increased resistance to chemical attack or mechanical abrasion, rapid hardening or shrinkage compensation. Moreover, the LMC carries out testing and contract work related to its competence.

Biography

De nationalité anglaise, Karen Scrivener est née en 1958. Au cours de sa carrière, ses travaux et sa recherche traitaient des domaines suivants: Identification du développement microstucturale pendant l'hydratation du ciment. Elaboration d'une approche multitechnique pour étudier la microstucture des ciments et bétons, avec accent sur la quantification par analyse des images d'électrons retrodiffusés. Caractérisation de l'auréole de transition de la pâte de ciment autour des granulats. Compréhension des processus de dégardation des bétons, en particulier le gonflement lié à la formation de l'éttringite retardée dans les bétons étuvés.
