摘要

Utilisation of locally available marginal soil as a construction material is one wise choice when improve its characteristics.Foundry sand (FS) is an industrial by-product obtained from foundry industries. In the present project, an attempt has beenmade to enhance geotechnical characteristics of locally available marginal red soil (RS) by addition of FS in 10%, 30% and50% to weight of dry soil. Further, the present project intends to blend a strong stabiliser like cement (C) to enhance thestrength and durability of mix made with red earth and 30% FS In this regard, 2.5%, 5% and 7.5% of cement is added to abovemix. Addition of 5% C mixed with 30% FS has shown unconfined compressive strength (UCS) of 1548.22 kPa. This strengthhas been achieved even after 12 cycles of alternate wetting–drying of specimens prepared by blending RS + 30%FS + 5%Cmix. The addition of 5% C passing the required durability criteria. Moreover, UCS of 3442.02 kPa has been achieved evenafter 12 cycles of alternate wetting–drying of specimens prepared by blending RS + 30% + 7.5%C. FS is a sustainable material,and it can be used as an alternative to natural river sand for enhancing geotechnical characteristics of RS.
