| To know the ability of Gypsum soils to losing the two water molecules (CaSO4.2H2O) in different temperature start from 40C° to 105C° for different Gypsum soils . Prepared the different samples from mixing lower Gypsum soil and higher Gypsum soil , taken from the surface soils horizon (Ap and C) to made Gypsum contents G1 (13.76%) , G2 (27.52%) , G3 (34.40%) , G4 (48.16%) , G5 (68.80%) The results shown the Gypsum contents G0 , G1 , G2 loosed of weight 47.59% , 46.95% , 48.59% respectively from samples weight after saturated in 75C° degree , and the Gypsum contents G3 , G4 , G5 , Gh shown losing in weight 49.35% , 49.71% , 50.16% , 51.21% respectively after saturation in same temperature . When the temperature continuous the losing weight continue in gypsum soils G0 , G1 , G2 to be 50.18% , 50.37% , 52.32% respectively from the weight after saturation in 105C° degree , and the Gypsum contents G3 , G4 , G5 , Gh losing weight 56.00% , 59.34% , 62.30% , 67.42% respectively from the weight after saturation in same degree . The results shown the water molecules being losing from (CaSO4.2H2O) to the Gypsum contents G3 , G4 , G5 , Gh in 75C° degree and higher until 105C° and the water molecules loss was 6.00% , 9.34% , 12.30% , 17.42% for the Gypsum contents G3 , G4 , G5 , Gh respectively in 105C° degree | ||
