CaO/SO 3 significantly affected the mechanical characteristics of phosphogypsum slag cement. The effectiveness of an alkaline activator can be improved by increasing its CaO content, which stimulates sulphate activation to some degree and causes significant hydrolysis …
Phosphogypsum (PG) is a solid grey, moist, fine-grained by-product powder generated during the production of phosphoric acid which has the chemical formula H 3 PO 4 …
Phosphogypsum is a grey, damp, fine grained powder, silt or silty-sand material with a max-imum size range between 0.5 and 1.0 mm, and 50–75% of particles finer than 0.075 mm. The specific...
The aim of this study is to give an overview and to evaluate the existing and potential uses of PG that extend from soil stabilization to cement and chemical industry and for agricultural to geotechnical, human impacts, and …
In this study, the volume stability, water stability and mechanical stability of geopolymers were tested, and the stability synergy mechanism between phosphogypsum, …
The use of phosphogypsum in a dose of 1.5 t/ha contributed to the significant accumulation of organic carbon in the topsoil of the studied sod-podzolic soils – in comparison with the control.
Phosphogypsum (PG) is a major industrial waste emitted during phosphate production. Facing the environmentally risky challenges posed by PG emissions and …
This paper explores the mechanism of efficiently modified phosphogypsum and constructs a model and evaluation system for heavy metal leaching and migration …
The use of reclaimed asphalt pavement (RAP) has become a common practice as… As phosphogypsum constitutes a large amount of solid waste material, its purification …
This BID contains an introduction, a general description of the fertilizer industry, a discussion of the physical and radiological characteristics of phosphogypsum, a discussion of the uses of …
