Estudio de la adición de arcillas calcinadas en la durabilidad de hormigones

Abstract: Estudio de la adición de arcillas calcinadas en la durabilidad de hormigones * Universidad Central de Las Villas, Santa Clara, Cuba ** Escuela Politécnica Federal de Lausana (EPFL), SUIZA Resumen Actualmente son bien conocidas las ventajas económicas y medioambientales de la sustitución del clínker de cemento por otros materiales cementicios suplementarios. Las arcillas calcinadas en forma de metacaolín han recibido por ejemplo especial atención en años recientes. Se conoce que estas adiciones, cuando se añade… Show more

“…There is thus a compelling need to use readily available and relatively cheaper cementitious alternatives and fines (fillers) in the production of SCC while not compromising its flowability, filling ability, segregation resistance, and strength as well as durability characteristics of SCC. The use of calcined clay and Limestone powder will alleviate, to a large extent, the cost and environmental effect associated with SCC production, and they have been used successfully in normal vibrated concrete [3] . More so, the durability of SCC can be enhanced by an improvement of its pore structure by positively altering its permeation properties.…”

“…Chindaprasirt y Rukzon (2009), señalan que las adiciones minerales tienen un efecto de densificación de la microestructura del concreto, debido a las reacciones puzolánicas estas se mezclan con la cal libre del concreto para formar nuevos productos hidratados que bloquean los poros existentes. Asimismo Castillo et al (2011), demostraron que las puzolanas mejoran la durabilidad de los hormigones producidos con estos materiales cementicios suplementarios.…”

“…In Argentina, the extraction of bentonites is located in Río Negro, La Pampa, San Juan, Neuquén and Mendoza provinces [6]. Today commercial clays are among the most important mineral resources, 90% is for building materials and aggregates [7]. The remaining 10% is consigned to other industries, including paints, adsorbents [8], bleaches [9], chemical and pharmaceutical products [10].…”
