Performance of alkali activated slag concrete mixes incorporating copper slag as fine aggregate
Journal of Cleaner Production, 2016In this present study, copper slag (CS) is proposed as an alternative to river sand as fine aggregate in alkali-activated slag concrete (AASC) mixes. The relative performance of alkali activated slag concrete mixes with CS as fine aggregate is compared to conventional Ordinary Portland Cement concrete (OPCC) mix in terms of their workability, strength ...

Nitriding of ilmenite and high-grade slag fines
2011Titanium bearing resources can selectively be chlorinated at temperatures below 200ºC if the TiO2in the feed is nitrided before chlorination. However, the nitriding reaction is highly endothermic, requires highly reducing conditions, is only thermodynamically favourable at elevated temperatures, and is affected by mass and heat transfer restrictions ...

Effect of the fineness of copper slag on the early hydration properties of cement–copper slag binder
Journal of Thermal Analysis and Calorimetry, 2019The early hydration heat and hydration process, hydration products and strength of binders containing 20% copper slag with different fineness has been studied. The ordinary Portland cement is taken as the comparison sample. Results show that the replacement of cement in the same proportion copper slag can prolong its induction period, reduce its early ...

Durability of Concrete with Copper Slag Fine Aggregate
SP-192: 2000 Canmet/ACI Conference on Durability of Concrete, 2000The lack of natural fine aggregate in Japan is serious because the commitment to protect the natural environment is increasing. Many concrete engineers are eager to find fine aggregate sources other than the traditional river and sea sand. Copper slag fine aggregate is expected to be one of the alternatives although the location where the copper slag ...

Properties of cement grout modified with ultra-fine slag
Frontiers of Structural and Civil Engineering, 2017The purpose of the study is to obtain a cement grout with improved performance. The grout mixes of the present study contain cement, ultra-fine slag (UFS), super plasticizer and water. Properties like flowability, bleeding, compressive strength and shrinkage of cement grouts have been studied.

Studies on Concrete Incorporating Copper Slag as a Fine Aggregate
Solid State Phenomena, 2015This paper investigates the possibility of application of copper slag as a waste byproduct from metallurgical factory Krompachy (Slovakia Republic) as a fine aggregate in concrete up to 40-50% replacement of natural filler. Results of these studies confirmed that it is possible to produce concrete with a mean compressive strength of greater 50 MPa at ...

Characterisation of LD slag fines by X-ray Diffraction
Metallurgical Research & Technology, 2015The reject of waste recycling plant (WRP) i.e. LD slag fines (0–6 mm) after metal recovery does not contain much of metallic iron, but this contains substantial quantity of calcium bearing mineral phases like mono, di and tri calcium silicates along with free lime content varying in the range of 11–15%.

Investigating the Slags of the Metallurgical Plants of Armenia at Fine Grinding
Steel in Translation, 2019In connection with the development of copper and molybdenum production in Armenia, it becomes necessary to develop a technology for processing the slags of the functioning metallurgical plants to extract valuable metals from the slags. It concerns the copper slags of Alaverdi copper-smelting plant with a content of FeO ∼50% and the molybdenum slags of ...
