Philippines, with a total of 7,107 islands, have one of the largest mineral resources in the world. The copper and gold deposits are considered to be among the largest in the world (Bureau of East Asian and Pacific Affairs, 2010). Mining minerals generate waste material called mine tailings. Impoundment of mine tailings is normally done to store these waste materials. One of the most common types used in impounding tailings is raised embankments because of its low economic cost. This impoundment uses natural soil, tailings, and waste rocks as the construction material. There are cases that raise embankments experience stability failure which can affect the environment and well-being of the community where it is situated. It is the interest of this study to assess the possibility of using mine tailings, specifically copper tailings, as a construction material. Index properties were first established following ASTM standards. From this, it was established that the copper tailings has plasticity. Unconsolidated undrained, consolidated undrained and consolidated drained test were conducted to determine the critical shear strength of the copper tailing. The copper tailings were tested having two relative densities namely, 60% and 90%. The effective critical angle of friction was found to have a range of 21°-28°. Since critical-state parameters are considered in the study, Cam clay model can be implemented so that to its behavior and failure mechanism can be predicted.

“…The slag used in Al-Jabri et al's publications [17][18][19][20] was possibly water-cooled based on information found directly from the suppliers' current website (assuming that the current industrial processes described on the website were the same at the time of Al Jabri et al's research). Some papers used copper tailings to replace sand aggregate [27,28]; these are not directly comparable to the water-cooled aggregate used in the present study. In the literature the slag was used to replace either fine or coarse concrete aggregates, thus further reducing the amount of the available experimental evidence for each type of slag and aggregate type respectively.…”

“…Moreover, Onuaguluchi and Eren (2012) proved that the use of pre-wetted copper tailings at 5% addition level seems to generate mortars with higher strength, elevated abrasion and important chloride resistance than control mixture. Thomas et al (2013) observed that copper tailing may also be utilized as M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 3 partial replacement of natural aggregates (till 60% replacement) for the manufacture of M25 grade concrete. Li et al (2010) investigated the possibility of using residues after iron recovery from iron ore tailings as raw materials for the preparation of cementitious material.…”
