The influence of lignosulfonate on the main physico-mechanical properties pigmented plaster
Incoming article date: 02.06.2017Abstract: field application of lignosulfonate as a chemical additive for use in gypsum compositions. The influence of lignosulfonate on the physical and mechanical properties of pigmented plaster. The work studied the effect of lignosulfonate on properties of gypsum as strength properties, water absorption, softening coefficient and the changing colors of the material. Established that the application of lignosulfonate to a considerable extent not only improves the physico-mechanical properties of the material, but also its operational durability of pigmented gypsum, which expands the scope of these materials.
Keywords: lignosulfonate, pigmented plaster, physico-mechanical properties, strength properties, water absorption, coefficient of softening, change of color, long service life
