Hormigón autocompactante con cenizas volantes

Abstract

El hormigón autocompactante (SCC) es un tipo de hormigón con una elevada capacidad de fluidez, capaz de fluir por efecto de la sola fuerza gravitatoria, sin necesidad de vibración. El SCC en estado fresco tiene características como: alta fluidez y deformabilidad, capacidad de llenado del encofrado por el solo efecto de la fuerza gravitatoria (capacidad de llenado), capacidad de inserción entre armaduras (capacidad de paso), estabilidad (estabilidad), es decir, capacidad del hormigón de permanecer homogéneo, resistencia a la segregación. Las propiedades en estado fresco pueden estimarse realizando ensayos de trabajabilidad como Slump Flow, L-Box, V- Funnel, U-Box, J-Ring. Después del curado, el hormigón autocompactante poseerá las siguientes propiedades: alta resistencia mecánica, durabilidad. La introducción de material ultrafino es la verdadera innovación porque tiende a crear una mezcla compuesta principalmente por partículas diminutas, capaces de transportar áridos gruesos. Se ha observado que las cenizas volantes, cuando se utilizan correctamente, mejoran las propiedades del hormigón tanto en estado fresco como endurecido.
