This study includes the effect of lime addition on engineering properties gypseous soil taken from a part Najaf- Karbla plateau (52, 48, 72% gypsum). Also this shows increase in proportion gypsum northwest direction area. Maximum dry density and optimum moisture content (2.065, 2.025 2.003) at 15%, 14% 15% respectively for three samples. The maximum decrease while increases with increasing rati...

Since the 60’s, many authors have reported presence of common silt-sized materials in Ebro valley, on surface formations and positions that given rise to several interpretations, sometimes contradictory. According references, three main terms are used (gypsiferous silts, loess flour-like gypsum) applied silts fine sands with gypsum accumulations. The two first carbonate contents up 40-50%, coar...
