Abstract
The study investigated the compressive strength of concrete with electric arc furnace (EAF) slag as partial replacement for coarse aggregate and cured for 28 days and 90 days. Percent replacements were set at 0%, 10%, 20% and 30%. Workability of fresh concrete decreased as percent replacement increased. Unit weight of hardened concrete increased as the amount of slag increased. After curing, specimens were tested and results showed that compressive strength generally decreased for all replacements. The least value occurred at 20% replacement in the 28-day curing period. While in the 90-day curing period, compressive strength increased having the peak value at 20% replacement. Also, compressive strength increased as the number of curing days increased. Statistical analysis showed that there is significant difference in compressive strength of concrete with percent replacement of slag to normal concrete. Differences also occurred in concrete cured for 90 days with concrete cured for 28 days.
