Performance of cohesionless soil partially replaced with building derived materials as a foundation material under static loading conditions

ABSTRACT

Sustainability is a prominent aspect of modern civil engineering. The development of infrastructures is making a significant mark on the nation’s economy worldwide. However this, in turn, is consuming and consequently depleting natural resources. Construction of new structures and renovation of existing structures yields a vast quantity of solid waste known as Construction and Demolition Waste (CDW). The present study aims at effective reuse of the building derived materials (BDM) as a substitute for loosely packed soils for foundation bed of substructures. A series of laboratory tests are performed to assess the strength characteristics of cohesionless soil partially replaced with varying percentages of BDM. It is observed that addition of 17-23% of BDM by weight helps to achieve the maximum strength. A numerical model is also developed in commercially available finite element software to predict the response of BDM - soil mixture.
