Geotechnical properties of limetreated gypseous soils · The natural and gypseous soil samples were treated with 3% lime (based on the pH test method suggested by Eades and Grim, 1966 ). The limetreated gypseous soil samples were cured for 2, 7 and 28 days at 20°C and 40°C. The second curing temperature of 40°C was considered for this research work in order to study the geotechnical behavior for ...

Stabilization of highly expansive soils containing sulfate using ... · During this reaction, lime creates a basic environment with pH of approximately which subsequently releases a large amount of calcium ions into the soil. Simultaneously, clay minerals break down into aluminum hydroxide and silicic acid as pH of the soil exceeds Dissolution of gypsum releases sulfate ions.
Two coal/petcoke grinding plants for MexicoThese are to be used in the cement plants of the group Cooperativa La Cruz Azul, – on the one hand in the plant in the province of Hidalgo, 80 km north of Mexico City, and on the other in the Lagunas plant in the province of Oaxaca in southern Mexico. In each of these cases, the Cruz Azul group is establishing a new production line here.
