Concrete is one of the most used structures in building construction due to its durability and strength. This research is to study the effects of Precious Slag Ball (PS Ball) to the characteristics of concrete. PS Ball is a waste product from the metal surface cleaning activity. The main objective of this research is to obtain the maximum compression for conrete as well as the density and water absorption rate. Conrete cube sample is 100mm x 100mm x 100mm is produced using concrete mixture without course aggregate meanwhile the fine aggregate for the conrete mixture is replaced with PS Ball at pre determined percentage of 0%, 10%, 20%, 30%, 40% and 50%. In conclusion, the maximum compressive strength achieved is 29.2 Mpa with 5% water absorption and density 2191.3 kg/m3 is for conrete mixture with 20% PS Balls. Therefore, the use of PS Ball as a substitute for aggregates in concrete mixture strengthens the concrete even more.
