Investigation of microstructural and mechanical properties of partially hydrated Asbestos-Free fiber cement waste (AFFC) based concretes: Experimental study and predictive modeling

Résumé

Asbestos-Free Fiber Cement waste (AFFC) was tested in this study as supplementary cementitious materials (SCM) in concrete formulations. The incorporation of AFFC leads to a drop in total porosity, compressive strength and Young modulus due to the creation of capillary voids. The optimum dosage of AFFC is 10%. Below this value, the created capillary voids are not interconnected enough to form percolation paths for gas flow. A modified Feret’s law combined with Eurocode 2 was proposed to predict the mechanical performance evolution with time. Finally, comparative tests between the performance of AFFC and limestone filler as SCM were also achieved.
