Abstract

Ultra-high-performance concrete (UHPC) is the essential innovation in concrete research of the recent decades. However, because of the high contents of cement and silica fume used, the cost and environmental impact of UHPC is considerably higher than conventional concrete. The use of industrial byproducts as supplementary cementitious materials, in the case of recycled glass powder and fluid catalytic cracking catalyst residue (FC3R), as partial substitution of cement and silica fume allows to create a more ecological and cost-efficient UHPC. This research presents a study to determine the possibility of partial substitution of cement by FC3R in a previously optimized mixture of ultra-high-performance concrete with recycled glass. The results demonstrate that compressive strength values of 150 and 151 MPa without any heat treatment can be achieved, respectively, when replacing 11% and 15% of the cement with FC3R, for a determined amount of water and superplasticizer, compared to 158 MPa obtained for the reference UHPC without any FC3R content. The rheology of fresh UHPC is highly decreased by replacing cement particles with FC3R. ----------RESUMEN---------- El concreto de ultra altas prestaciones (UHPC) supone el máximo exponente en la investigación sobre concretos especiales en las últimas décadas. Sin embargo, debido a su elevado contenido en cemento y humo de sílice, el costo e impacto ambiental del UHPC es considerablemente superior al del concreto convencional. El empleo de co-productos industriales como materiales cementantes suplementarios, caso del polvo de vidrio reciclado y el residuo de craqueo catalítico (FC3R), en sustitución parcial del cemento y del humo de sílice permite crear un UHPC más respetuoso con el medioambiente y más eficiente en costo. Esta investigación presenta un estudio para determinar la posibilidad de sustitución parcial de cemento por FC3R en una mezcla previamente optimizada de UHPC que incorpora polvo de vidrio en su composición. Los resultados muestran que es posible alcanzar una resistencia de 150 y 151 MPa sin ningún tratamiento térmico al reemplazar un 11% y 15% del peso de cemento por FC3R respectivamente para una cantidad de agua y superplastificante determinadas, en comparación con los 158 MPa obtenidos para la muestra de referencia sin FC3R. La reología del UHPC se ve fuertemente afectada cuando se sustituye cemento por FC3R.
