Lignosulfonato, a hydrated and complex molecular molecule, has the ability to reduce the surface energy of the solid-liquid interface. During hydration, its macromolecular anions can negatively charge the cement particles. This adsorption reduces the zeta potential.

Áademas, it can prevent flocculation of fine cement particles. Its polar hydrophilic organic chain can keep the cement particles separated by electrostatic repulsion.

Several factors, including cement and admixture composition, affect compatibility. The usual dosage of a water reducer is 0.3- 0.5% liquid by weight of the cement.

Higher dosages of a water reducer can cause excessive retardation and bleeding. Incompatibility between the cement and water reducer can lead to rapid loss of workability. Je'exbix, high dosages of a water reducer may produce a reduction in the concrete’s flexural strength, séebkunsik u ts'a'abal le pasta cementoo', yéetel u yáanta'al u k'astal u fluidez.
