StarLig has good deflocculating properties in cement powder and it can therefore be used in the dry grinding raw material processing phase. Finer powders can be obtained and so increase the yield of grinding mills. When used in concrete mixes, StarLig lignosulfonates increase the fluidity of the mass, reducing the amount of water required and at the same time improving the rheological properties.
In specific applications, it is also possible to use StarLig products as binders, improving mechanical resistance, plasticity and distortion resistance of the structure. The possibility to vary sugar content leads to many applications regarding to regulation of setting times. In the plaster sector, apart from fluidifying, StarLig can be used to retard setting times. This means that workability of mixtures can be improved.
Sodium lignosulfonate, calcium lignosulfonate or magnesium lignosulfonate can all be applied, depending on the formulations. As dispersants, the purified premium StarLig lignosulfonates are highly recommendable in order to substitute other dispersing agents. This gives a direct positive impulse to the process efficiency.
