Hydration of Tricalcium and Tribarium Aluminate : Effect of some water reducing admixtures

The ability of plasticizers and superplasticizers to reduce the water-cement ratio without changing the workability of concrete is a well-known fact. On the other hand, they may improve and / or facilitate the conditions the conditions of cement handling. Thus in this thesis, the effect of the presence of two different water-reducing admixtures, namely, calcium lignosulfonate (CLS) and sodium salt of naphthalene formaldehyde sulfonic acid polycondensate (NFS) on the hydration process of each of C3A and B3A with gypsum was studied.
