Cement mixtures containing copper tailings as an additive: durability properties

Onuaguluchi, Obinna; Eren, Özgür (ABM, 2012-12)

The effects of copper tailings as an additive, on some durability properties of cement mixtures were investigated. In each mixture, copper tailings addition levels by mass were 0%, 5% and 10%. Compared to the control ...
Copper tailings as a potential additive in concrete: consistency, strength and toxic metal immobilization properties

Onuaguluchi, Obinna; Eren, Özgür (NISCAIR, 2012-04)

This paper presents the results of a study investigating the consistency, hardened and toxic metal immobilization properties of concretes containing copper tailings as an additive. To compare the effects of copper tailings ...
Durability-related properties of mortar and concrete containing copper tailings as a cement replacement material

Onuaguluchi, Obinna; Eren, Özgür (Thomas Telford, 2012-05)

This paper reports the results of research investigating the impact of copper tailings on some durability properties of cement pastes, mortars and concretes. Four mixtures incorporating copper tailings at 0% to 15% cement ...
Properties of Cement Based Materials Containing Copper Tailings

Onuaguluchi, Obinna (Eastern Mediterranean University (EMU), 2012)

ABSTRACT: Increasing demands for copper and copper allied products have made the processing of low grade ores with high volume waste output unavoidable. Presently, billions of tons of copper tailings can be found in major ...
Recycling of copper tailings as an additive in cement mortars

Onuaguluchi, Obinna; Eren, Özgür (Elsevier, 2012-12)

Increasing demands for copper and copper allied products have made the processing of low grade ores with high volume waste output unavoidable. Presently, billions of tons of copper tailings can be found in major copper ...
Reusing copper tailings in concrete: corrosion performance and socioeconomic implications for the Lefke-Xeros area of Cyprus

Onuaguluchi, Obinna; Eren, Özgür (Elsevier, 2016-01)

Copper mining and processing activities at an abandoned mine in the Lefke-Xeros area of Cyprus have created a huge environmental contamination problem in the locality. As an alternative mitigation and management measure, ...
A REVIEW ON THE UTILIZATION OF BY-PRODUCTS OF BIOMASS ENERGY PRODUCTION AS CEMENT REPLACEMENT MATERIAL IN CONCRETE

Onuaguluchi, Obinna; Eren, Özgür (2010-09)

Biomass energy production is considered an environmentally friendly way of providing energy because of its CO2 neutrality. Unfortunately, the disposal of particulate residue from biomass combustion has thrown up a ...
Rheology, strength and durability properties of mortars containing copper tailings as a cement replacement material

Onuaguluchi, Obinna; Eren, Özgür (Taylor & Francis, 2012-05)

This paper investigates the suitability of copper tailings as a cement replacement material in mortars. The impact of copper tailings at 0%, 5%, 10% and 15% cement replacement level by mass on the rheology, mechanical and ...
