Most of the world's energy demands are met from
fossil fuels, so the amount of sulfur released as a result of petroleum
processing increases. In recent years, there has been a significant increase in
studies investigating the usability of sulfur as a building material due to
increased sulfur reserves and applications where sulfur is used as a binder in
concrete have been realized. In this study, it was aimed to determine the
compressive strength of sulfur polymer concrete (SPC) and to compare the
results with traditional Portland cement concrete (PCC) with similar
compressive strength. Firstly, the sulfur modification was performed using 2.5%
bitumen by weight for the preparation of SPC in the study. Differential
scanning calorimetry (DSC) and scanning electron microscope (SEM) analyzes were
performed on the prepared modified sulfur (MS) samples. 28 days compressive
strengths of SPC concretes prepared using MS were determined and PCC mixing
ratios with similar compressive strengths were obtained using the same
aggregates. The casting of SPC and PCC mixtures were performed and compressive
strength tests were carried out at the end of 7, 28 and 360 days. Also, due to
the early setting feature of SPCs, compressive strength tests at the end of 1
and 24 hours was determined, unlike PCCs. As a result of the experiments, it
was determined that 28% of the SPC's 28-day compressive strengths reached at
the end of 1 hour, while PCCs reached 82% of their 28-day compressive strength
at the end of the 7 days. While long-term compressive strength values of PCCs
increased, there was a decrease in the compressive strengths of SPCs.
