Analysis of Swelling Characteristics of Expansive Soil

Syed Jahanzaib Shah1, Ali Nawaz Mengal, Saeedullah Jan Mandokhail

Abstract


Swelling and expansion are important characteristics of soil. The expansive soil can cause many problems in the foundation due to settlement in the form of shear. Therefore behavior of the expansive soil should be investigated properly before structural design. In this study the effects of swelling and expansive characteristics of soil are analyzed by experimental work. Moisture content and dry density are found to check the effect of their variation on the swelling of soil. Swell potential test and swell pressure test are carried out according to ASTM standards. From the obtained result it is observed that with the increase in the initial moisture content, swelling potential decreases and the increase in dry density causes decrease in swelling potential.
