Utilization of Recycled Construction and Demolition Waste in Backfill Soil
https://orcid.org/http://orcid.org/0000-0001-8936-9880
India requires a large landfill area for the disposal of construction and demolition waste (C&DW) generated during maintenance, renovation, or destruction of different structures. India produces millions of tonnes of C&DW and the capacity for recycling is less than 2 percent. As a result, India must establish a strategy for reducing, reusing, and recycling C&DW. This study presents the efficacy for use of C&DW as a reinforced material to be mixed with backfill soil in retaining walls. Various index and engineering properties of soil and C&DW, including compaction parameters, and shear parameters are determined and compared for different C&DW and soil proportions. The compaction tests and triaxial compression test showed that the best results are achieved with 37.5% replacement of soil by C&DW. When 37.5% of soil is replaced by C&DW, the Optimum moisture content and maximum dry unit weight values were observed to be increased by 6.95% and 2.06%, respectively, while the cohesion decreased by 30.35% and the internal friction angle increased by 85.44%. The study emphasizes the potential application of C&DW as a reinforcing material in the backfill of the retaining walls.
