Regarding the addition of liquid sulfur to the CSH formation, there is limited scientific literature available on this specific topic. It is worth noting that elemental sulfur has unique chemical properties, including reactivity and potential for phase transformations. If liquid sulfur were to be introduced into the concrete mix, it could potentially react with the components of cement, including CSH.

The potential reactions between liquid sulfur and CSH would depend on various factors, such as the concentration of sulfur, temperature, and the presence of other compounds. It is possible that the sulfur could react with calcium ions in CSH, leading to the formation of calcium sulfides or other sulfur-containing compounds. These reactions could potentially alter the structure and properties of CSH, affecting the strength and durability of the concrete.

No. My knowledge to the subject matter can be limited but my basics tell me it will lead to formation of sulphuric acid .. and thus will be undesirable for a good concrete.

mixing liquid sulfur into concrete mix would introduce incompatible materials and could negatively impact the performance of the concrete.
