The use of sulfonated melamine–formaldehyde resins as dispersants with inorganic materials was investigated, and the effect of these dispersants on the rheology of cement pastes was studied. The improvement in compressive strength of sand and mortar was also investigated. Results show that these polyanionic resins are effective dispersing agents when they are mixed with inorganic materials. Significant improvements in the flow and compressive strength of these systems can be realized when small quantities of the water‐soluble polymers are added. The effect of reaction conditions on the molecular structure and its effect on performance is discussed.
