The impact of clinker grinding aids (GAs) based on amine, glycol, or phenol on static yield stress (t0) of cement pastes is not well understood. Results obtained from this project have shown that GA molecules remain active after the grinding process and provide variations in cement properties, whether in the fresh or hardened states.
