Shear strength of recycled construction materials intended for use in vibro ground improvement

摘要: Coarse granular materials are widely used in construction. The required mechanical characteristics of the determined by specific civil engineering application. These coarse often obtained quarrying intact rocks. Growing environmental awareness, need to ensure sustainability construction industry, and public concern safeguard countryside limit use sites encourage industry look for alternative applications. work described this paper was undertaken examine waste regard their potential replacing quarried stone vibro ground improvement processes. Three were considered: quarry waste, building debris crushed concrete. examined under various testing conditions: dry, wet, mixed with 10% 20% clay slurry. Tests carried out a 305 mm × direct shear box. performance these mater...
