原始语种摘要: This article investigates the use of phosphogypsum, generated from the production of phosphoric acid, as a material for inclusion in cement compounds (mortar) at 10%, 20% and 30% by mass relative to the cement. The mechanical strength and thermal insulation capacity of gypsum-containing cement samples were evaluated. Mortars containing gypsum did not perform as well as the reference mortar in terms of mechanical strength, but their bending resistance was higher. In terms of thermal insulation capacity, the mortars containing gypsum performed better, especially the mortar containing 30% phosphogypsum.
