Summary:

Utilizing excavated soil from construction and demolition activities as partial substitute of natural sand can lead to low embodied constructions. The talk attempts to give an insight into the development of 3D printable stabilized earth-based materials using excavated soil, and highlight the engineering performances of the developed materials. In this research, the effectiveness of two binder systems – ordinary Portland cement (OPC) and combination of OPC and blast furnace slag (GGBS), in stabilizing excavated soil for 3D-printable formulations was investigated. The talk will elucidate on the role of clay (in soil) in modifying the rheological parameters, flowability and “green” strength that are critical for high-quality extrusion and buildability during 3D printing. Finally, influence of the binder systems on clay stabilization and hardened performances including strength, permeability and moisture sensitivity of the materials will be discussed.
