Valorization of Fine-Fraction CDW in Binary Pozzolanic CDW/Bamboo Leaf Ash Mixtures for the Elaboration of New Ternary Low-Carbon Cement

Autor: Javier Villar-Hernández, Ernesto Villar-Cociña, Holmer Savastano, Moisés Frías Rojas

Publikováno v: Resources, Vol 13, Iss 7, p 100 (2024)

This paper presents the characterization of a binary mixture of construction and demolition waste (CDW) and bamboo leaf ash (BLAsh) calcined at 600 °C (novel mixture) and the study of its pozzolanic behavior. Different dosages in a pozzolan/Ca(OH)2

Multi-Technique Characterization of a Fine Fraction of CDW and Assessment of Reactivity in a CDW/Lime System

Autor: Moisés Frías, Raquel Vigil de la Villa, Sagrario Martínez-Ramírez, Lucía Fernández-Carrasco, Ernesto Villar-Cociña, Rosario García-Giménez

Publikováno v: Minerals, Vol 10, Iss 7, p 590 (2020)

This study analysed the fine particle (4AH13, C4AcH12) were identified during the pozzolanic reaction in CDW/lime system. Therefore, this type of waste can be reused as supplementary cementitious material with low-medium pozzolanic activity.
