Treatment of expansive soils with quality saline pore water by cyclic drying and wetting
Expansive soils can be found in many parts of the world particularly in arid and semi-arid regions. These soilspose a significant hazard to civil engineering structures due to its high swelling and shrinkage potential. This paperpresents the results of an experimental program developed to investigate the effect of cyclic drying and wetting on theswelling potential of expansive soils with variou...
متن کاملPotassium status of two clayey calcareous soils treated with zeolite under wetting-drying cycles
Zeolite application to clayey soils may change potassium (K) pools distribution and its release rate. To test this hypothesis, two heavy-textured calcareous soils with different mineralogy (smectitic and mixed by XRD) from southern Iran were selected. Experiment was a completely randomized factorial arrangement. Treatments consisted of two soils and two zeolite levels (0 and 5%) and wetting-dry...
متن کاملthe effect of temperature on the behavior of an expansive soil during drying and wetting cycles
in this research the mechanical behavior of an expansive soil (with different pore fluid) was investigated under the constant and variable temperature through experimental tests. the soil samples with different pore fluid (distilled water, nacl and cacl2 with concentration of 250 gr/lit) were prepared by static compaction method. experimental testes were conducted in two modified odometer under...

متن کاملMineralization of Nitrogen in Soils Amended with Dairy Manure as Affected by Wetting/Drying Cycles
Interest in manure management and its effects on nitrogen (N) mineralization has increased in recent years. The focus of this research was to investigate the N-mineralization rates of different soil types in Coastal Plain soils and compare them to a soil from Illinois. Soils with and without dairy composted manure addition were subjected to different wetting/drying cycles [constant moisture at ...
