swell- shrink behavior of expansive soils under different surcharge and water qualities
expansive soils are of the kind the volume of which will be changed to extremes by being exposed to varying conditions of moisture. this volume change is a serious menace to structures built on these types of soils. throughout the present research the potential of volume change in these soils was investigated when exposed to the phenomenon of wetting and drying. for the purpose, samples of a st...
متن کاملan investigation of swell-shrink behavior of an expansive soil
expansive soils show swelling and shrinkage behavior when subjected to cyclic wetting and drying. the variation in water content influence the volume change in this kind of soil. these volume changes can cause ground movement which may result in damage to the buildings and structures. to study the behavior, a number of successive wetting-drying cycles were conducted on a statically compacted ex...
متن کاملBehavior of Flexible Pavements on Expansive Soils
This investigation discusses the findings on analysis results of a pavement structure constructed on a relatively expansive material consisting mainly of brown clayey silt in Tebessa, Algeria. Cores were brought to the laboratory from a piece of roadwork. Remolded samples were taken from subgrade of a deteriorated road. The soils were generally found to be of medium plasticity and of a medium t...
متن کاملPerspective: The List of Potential Volume-sensitive Chloride Currents Continues to Swell (and Shrink)
The protein for the swelling-activated chloride conductance is one of the few ion channels left for which we do not have a universally acceptable clone. In this brief note, I hope to describe why chloride channels in general, and I Cl.swell in particular, have been difficult to pin down. Dr. Strange describes why he believes the pICln protein is not I Cl.swell . I agree. In 1995 we demonstrated...
متن کاملGenomes on the shrink.
B ecause genetic events do not fossilize, we are forced to deduce the evolution of bacterial genomes by comparing the features of contemporary organisms. This comparative approach has exposed many of the alterations endured by bacterial genomes (bouts of expansion and contraction or changes in base compositions), but such reconstructions are often imprecise, and sometimes incorrect, because the...
