The Use of Industrial Byproducts as Fillers in Self-Compacting Concrete

This paper presents results of the study conducted on five series of Self-Compacting Concrete (SCC) made with different mineral fillers. Beside the reference series, made with limestone powder as mineral filler, three series were made with 50% of mass replacement of limestone powder with ground recycled concrete, and one made with 50% of mass replacement of limestone powder with fly ash. Slump flow, time t500, density, and temperature were tested on fresh series, while compressive strength and water permeability were tested on hardened concrete. All of the series showed acceptable properties, providing a positive impulse for use of industrial byproducts as mineral fillers for SCC production
