Abstract
AbstractIndustrial wastes like ground granulated blast furnace slag (GGBFS) and rice husk (RH) ash were utilized to improve the strength of subgrade soil available locally in Vembakkam region of Thiruvannamalai district in Tamil Nadu. To improve the bonding between soil and industrial wastes, 4% quick lime was mixed with the soil along with the industrial wastes GGBFS and RH ash. Soil was identified as clayey sand (SC) based on its index properties. GGBFS was varied in proportions of 20–40% by weight of SC and RH ash was added in quantities of 10–50% by weight of SC, to decide the best dosage of GGBFS and RH ash to be mixed with SC so as to achieve maximum soil strength after curing for 3 days. Based on the unconfined compressive strength (UCCS) test and soaked CBR test, ideal percentage of GGBFS and RH ash was found to be 30% and 20%, respectively. For SC with 4% lime, 30% GGBFS, and 20% RH ash, UCCS was observed to increase by 3.36 times that of virgin soil and soaked CBR value was found to increase by 9.23 times that of virgin soil after 3 days curing period.KeywordsClayey sandQuick limeGround granulated blast furnace slagRice husk ashUnconfined compressive strengthSoaked CBR strength
