An experimental study on swelling properties of expansive soil treated with iron furnace slag

الملخص EN

Using industrial waste materials in the treatment of problematic soils is anenvironmentally friendly and cost-effective technique.

It helps in decreasingdisposal issues induced by various industrial wastes.

Also, it is crucial tounderstand the behaviour of these waste products before use.

This paper presentsexperimental research in the treatment of expansive soil by the utilization of ironfurnace slag.

Laboratory program was performed to examine the effect of ironfurnace slag on enhancing the engineering properties of expansive soil.

Severaltests included liquid limits, plastic limits, free swell percentage, swelling pressure, and unconfined compressive strength were conducted on untreated and treatedsoils.

The efficiency of adding 0, 2, 4, and 6 percentages of iron slag to the soil wasinvestigated.

The results of the natural and iron slag stabilized soils showed thatiron slag has a notable effect on strength parameters and considerable improvementin plasticity and swelling properties.

The addition of iron slag to the soil increasedthe unconfined compressive strength while reduced the swelling potential of soil.

It is concluded that the utilization of iron slag to improve the properties ofexpansive soil is successful and useful
