Abstract

Precisious slag ball (PS Ball) is a waste of residual steel processing which was originally liquid and then recycled using Slag Atomizing Technology (SAT) technology into small, compact granules. . PS ball has a grain size of 0.1-4.5 mm with a higher specific gravity and hardness than sand. The PS ball's granular structure is very powerful, weather resistant, and not easy to wear, so it can be used in SCC concrete as a replacement for fine aggregate. The purpose of this study was to examine the performance of SCC concrete with a PS ball as a substitute for some of the fine aggregate. The concrete performance of SCC studied consisted of fresh concrete performance and concrete mechanical performance. Concrete performance includes filling ability and passing ability, while concrete mechanical performance consists of compressive strength and concrete tensile strength. The specimens of 4 variations were obtained in PS Ball quantity, namely 0%, 10%, 20%, and 30% of the fine aggregate weight. The findings showed that the use of the PS ball as a fine aggregate would enhance SCC concrete's filling and passing abilities. The use of the PS ball as a replacement for fine aggregate will improve concrete's compressive strength and tensile strength by up to 20 %.
