Abstract
In large cities with a growing population, the expansion of construction and demolition (C&D) waste of buildings can lead to the annual production of millions of tons of waste. Any solution for inexpensive, rapid, and accurate identification of these depots' layering structure and composition can greatly benefit urban management. Geoelectric methods can serve as a simple, cost-effective, and sufficiently accurate means of identifying these materials. In this study, the layering structure of C&D waste buried in line 4 of the Hesar landfill in Karaj City, Iran, was determined using a geoelectric method involving the assessment of electrical resistivity variations in both vertical and horizontal directions. Wenner-Schlumberger array was utilized for the measurements, and 2,870 electrical resistivity points were collected. RES2D-INV software was utilized to interpret the data and plot geological sections. In addition, a series of laboratory tests, including Sieve analysis and water content, were performed on samples collected by continuous core boring to better understand the waste composition. According to the study results, compared to the field data, it was concluded that the ERT could accurately predict the changes in various soil layers, aggregate sizes, and water content. In addition, data from boreholes revealed that most of the materials buried in this depot are concrete. The results of this study can assist urban management in recycling C&D waste. Recycling C&D waste recovers some economic value from C&D waste, clearing out C&D waste depots and eliminating the environmental desirability issues that they can cause in surrounding areas.
