Modélisation de l'élasticité d'une pâte de ciment au jeune âge

摘要: ABSTRACT Concrete is a complex multi-scale composite involving multi-physics processes. As it the only evolving component, cement paste has major influence on mechanical properties of concrete at early age. The homogenization theory for disordered media used in order to model development elastic during its hydration. morphological refers two types C-S-H distinguished by many authors: high density or inner products build up layers surrounding anhydrous particles, while low outer play role porous matrix. effective Young's modulus evolution with respect degree hydration proves be excellent agreement experimental results available literature.
