X-ray CT Analysis of FNS Mortars Mixed with Converter Slag Fine Aggregate

Aggregate is an indispensable component in concrete occupying nearly 65-80% of the total volume, whose effects on concrete performance are rarely studied [1]. Due to their inert and impervious characteristics, the durability of concrete is also influenced by the quality of aggregates. To meet the global demand for concrete in the future, it is becoming a more challenging task to find suitable alternatives to natural aggregate for preparing concrete [2]. Hence, the use of alternative sources for natural aggregates is becoming increasingly important.
