In seasonally frozen regions,the frost-heave properties of soil play a significant role in its upper-structure performance and durability.To investigate the frost-heave behaviors of saturated,compacted silty clay soil...
Limited studies dealt with the expansive unsaturated soils in the case of large-scale model close to the field conditions and therefore, there is much more room for improvement. In this study, expansive (bentonite–s...
Some disadvantages associated with conventional brick masonry are: high cost of construction, lower compressive strength and less durability. In order to resolve these problems, a new technique of constructing walls u...
