Solid waste phosphogypsum (PG) generated during phosphoric acid production was used as the sole raw material to prepare a new paper-free and fiber-free plasterboard. Dehydrated PG was granulated with water, press-formed and hydrated with intermittent pressing into paper-free and fiber-free plasterboards with bending strength …
1. Introduction. Phosphogypsum (PG) is among the by-products emitted by the phosphorus chemistry industry. About 5 tons of PG are emitted for each ton of phosphoric acid produced [1, 2], and its reaction is shown in Eq (1).About 300 million tons of PG are added annually, and total stockpiles exceed 600 million tons [3].PG is complex …
The objective of this study is to unravel the modification mechanism of a coupling agent on the water sensitivity of phosphogypsum asphalt mortar. The adhesion process of phosphogypsum asphalt mastic modified with three kinds of coupling agents (KH-550, KH-570, and CS-101) and raw phosphogypsum to the aggregate minerals …

Phosphogypsum (PG), the main industrial by-product of phosphate fertilizer industry, primarily consists of calcium sulfate dihydrate. However, it contains various impurities with variable quantities depending on the origin of the phosphate rock. These impurities can restrict the reuse of phosphogypsum as a secondary primary resource.

The P 2 O 5 and F are found in three forms: (i) on the surface of phosphogypsum crystals with water-soluble compounds (H 3 PO 4, Ca(H 2 PO 4) 2 ·H 2 O, NaF); (ii) substituted in the lattice of phosphogypsum crystal (effectively solid solutions of CaHPO4·2H 2 O or Na 2 SiF 6) in PG; and (iii) as insoluble compounds (Ca 3 (PO 4) …
1. Introduction. Phosphogypsum is the main by-product during the manufacture process of phosphoric acid from phosphate rock. 1 Because phosphoric acid is one of the most important composition in fertilizer industry, the amount of phosphogypsum rapidly increases at a rate of about 70 million tons per year with a very low utilization …
Solid waste phosphogypsum (PG) generated during phosphoric acid production was used as the sole raw material to prepare a new paper-free and fiber-free plasterboard.

Phosphogypsum (PG), a byproduct during the phosphoric acid production process, also known as the wet process, contains complex and diverse impurities, resulting in low utilization and considerable accumulation. This leads to a massive waste of land resources and a series of environmental pollution problems. Given the current urgent …
The phosphogypsum is a by-product of the phosphate fertilizer industry. It has accumulated over several decades, and not only takes up a large amount of land, but also poses a significant risk to the environment and resource waste. In order to promote the use of phosphogypsum, its hydration hardening characteristics are studied using a …
