Description
Wonchang Kim, Taehyung Kim, and Taegyu Lee wrote this research paper, published in 2024. It tests concrete in which part of the cement is swapped for bio-sulfur, a sulfur recovered from landfill gas by microbes, blended with limestone.
Five blends were prepared at different sulfur-to-limestone ratios. Too much limestone wrecked workability and halved strength, so an even ratio won. With that blend, adding more bio-sulfur raised compressive strength by up to twelve percent. Wave speed through the specimens rose in step and did not depend on the water ratio. Statistics confirmed the effects were real. X-ray analysis showed the usual cement crystals early, then new magnesium and calcium sulfur-bearing hydrates by day twenty-eight. The authors say the waste sulfur route is a genuine, greener cement substitute.
