Exposure of lime treated expansive soil to sulphatic compounds are known to develop
distresses due to the formation of ettringite or thaumasite, causing excess swell and …

The efficacy of lime treatment to improve sulfatic soils has previously been explored. The
formation of ettringite (E) and thaumasite due to the reaction between lime–clay–sulfate in …

This study comprises two distinct but interrelated parts. The first part involves optimizing the
conditions for the conversion of phosphogypsum to a Ca (OH) 2 and Na2SO4 solution. The …

Phosphogypsum (PG) is the principal byproduct generated by the phosphoric acid (H3PO4)
production sites. At these sites, one ton of phosphate rock leads to the production of 1.7 tons …

The study of a gypsum single crystal was carried out using in situ thermo‐Raman
spectroscopy in the temperature range of 80–870 K. The conventional peak fitting approach …

Abstract [eng] In this master's thesis, the use of modified phosphogypsum in binding systems
is analyzed through experimental research. Phosphogypsum, as a waste product of AB" …
