Quantification Methodology for the Use of Sulphur Concrete in Precast Applications

This methodology is applicable to processes that involve the substitution of calcium and/or magnesium carbonate-derived ("Portland") cement with an alternative binder such as a modified heated sulphur product during the production of concrete and other concrete-based products such as pre-cast pipe, paving stones, slabs and tanks.

Unlike concrete made from Portland cement (which can be cold mixed), concrete made with modified heated sulphur needs to be heated during production. Despite the need to be hot mixed (with heat likely obtained from the combustion of fossil fuels), concrete and cement products made with modified heated sulphur releases far fewer greenhouse gas (GHG) emissions than concrete made with Portland cement. Modified heated sulphur avoids the process emissions released in the calcination process of clinker production as well as the combustion emissions typically generated to supply heat to the calcination process.
