Plaster for internal coatings of partition walls incorporating untreated phosphosypsum
Palabras clave:
Phosphogypsum, Gypsum, Plaster, CoatingResumen
Industrial by-product phosphogypsum (PG) was recovered, with no pretreatment, into plaster (G) for internal coatings of partition walls. The hydration properties of five plasters (100%G, 100%PG, 25%PG + 75%G, 50%PG + 50%G, and 75%PG + 25%G, by weight) were investigated, including water requirement for normal consistency, setting time, compressive and flexural strength, bond strength, and water absorption. Although G and PG are chemically similar, PG presented a specific surface area and total pore volume greater than G, demanding more water. The 75/25 untreated PG/G plaster fits all the technical requirements to be applied as internal coatings for partition walls.
