The purpose of this study is to develop a new type of backfill material so-called controlled low-strength material (CLSM) with the recycling of various types of waste materials, including fly ash (FA), ground granulated blast-furnace slag (so-called slag), and especially copper mine tailings (CMT). By the way, this study also provides a good solution to not only consume a large quantity of industrial solid wastes but also address the shortage of natural resources used in construction activities and thus reducing the negative effects on the environment. Different proportions of CLSM mixtures were prepared and tested for engineering properties, including flowability, setting time, and compressive strength development in accordance with the relevant standards. In addition, a cost analysis was also performed to evaluate the potential application of such material in real practice. The experimental data show that the developed CLSM mixtures had good flowability high tube flow values of 22 ± 1cm. Moreover, all of the CLSM mixtures reached the initial and final setting within 4 hours and 24 hours, respectively. After 28 days of curing, the highest compressive strength value of approximate 41 MPa was obtained at the CLSM samples containing 70% CMT, 5% FA, 15% cement, and 10% slag. On the other hand, the materials cost for producing each m3 of CLSM was in the ranges of 24.1 to 25.6 USD. The results of this study further demonstrated a high potential for the development of green CLSM applying for backfill applications with the recycling of waste materials including FA, slag, and CMT.
