Durability of sulfur concrete in various aggressive environments
Highlights ► Sulfur concrete samples are made of modified secondary sulfur, sand, and fillers. ► Durability of sulfur concrete is investigated in 10% HCl, 20% H2SO4 and 3% NaCl. ► Compressive strength loss is higher for samples treated by HCl compared to H2SO4. ► Compressive strength loss is negligible after treatment in NaCl. ► Apparent porosity increase is in agreement with compressive strength loss.
Abstract Durability of sulfur concrete with different fillers, as well as Portland cement concrete, was tested in the solutions of HCl, H2SO4, and NaCl. Regarding mass changes, in the solutions of HCl and H2SO4 sulfur concrete with talc and fly ash exhibited higher durability, while in NaCl samples with alumina and microsilica were better. The type of filler did not affect durability regarding compressive strength. Strength loss was higher in the solution of HCl comparing to H2SO4, while negligible in NaCl which is in accordance with apparent porosity increase. Portland cement concrete after two months lost 20% of mass.
