Influence des interactions physico-chimiques entre particules et composés organiques sur la stabilité de mousses minérales

Abstract : Cement-based mineral foams are solid porous materials and presentvery interesting insulating properties. Such materials are used in the constructionsector in order to reduce the energy consumption of houses. However, theproduction of these materials can be difficult because of the kinetic competitionbetween foam stability and cement setting. Cement-based mineral foams areextremely complex materials because of the number of components and all theirinteractions. The objective of our study is to get insight into the interactions betweenmineral and organic compounds and to understand their role in the stabilizingmechanisms. Our strategy was to study a model system, sufficiently close the realone to be representative, and sufficiently simple to identify the contribution of thedifferent components. We used as a foaming agent a surfactant exhibiting acharacteristic peak in UV-visible spectroscopy in order to determine its function andposition in the complex system. We first worked on unfoamed slurries, then westudied thin liquid films and the foamed materials.
