Resumen

Para la preparación del árido CG-FA (CFA) se utilizaron GGA de carbón (CG) y cenizas volantes (FA). El hormigón CFA (CFAC) se produjo sustituyendo el árido de piedra pómez natural (NPA) por CFA. Los parámetros óptimos de calcinación se obtuvieron mediante un ensayo ortogonal con la conductividad térmica como criterio de evaluación. La conductividad térmica, la estructura de los poros y la micromorfología se caracterizaron para evaluar las propiedades de aislamiento térmico. Los resultados mostraron que los parámetros de calcinación óptimos eran una temperatura de precalentamiento de 500°C durante 20min y una temperatura de calcinación de 1000°C durante 10min. La conductividad térmica disminuye un 24.31% con el 100% de CFA. El llenado de los poros con productos de hidratación conduce a una transición de macroporos (>1μm) a poros de transición (0.01-0.1μm) y poros capilares (0.1-1μm), lo que complica y retrasa el tiempo de transferencia de calor.
