ABSTRACT

This study investigated the influence of basic oxygen furnace slag (BOFS) as partial coarse aggregate in the pullout strength of anchor bolts installed in concrete. To design the different concrete samples, natural coarse aggregates were replaced by mass with 19-mm size BOFS from 0% to 50%, with 10% intervals. Fifty-four 150mm x 300mm cylindrical concrete specimens were tested for compressive test in accordance with ASTM C39-09, while ninety 350mm x 350mm x 150mm concrete samples with cast-in-place 12-mm diameter Grade 36 hexagonal headed anchor bolts were subjected for pullout test in conformity to the ASTM C900-06 test procedures. With increasing BOFS percentage, it was observed that there was a gradual decrease in a slump of the concrete mixture, an increase in compressive strength, and an increase in pullout strength based on the test results. Concrete samples with 50% BOFS from the experiment exhibited the highest compressive strength and pullout strength of the anchor bolts throughout the 7, 14, and 28 days of curing. Through correlation and regression analyses, it was found that there was a significantly strong positive linear relationship between the pullout performance of anchor bolts and the percentage of BOFS as partial coarse aggregates in concrete at all ages. The pullout capacity of the concrete with BOFS exceeded the breakout strength predicted by NSCP 2015.
