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 ...

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%.

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 ...

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 ...

Effect of Slag Fineness on the Development of Concrete Strength and Microstructure
"SP-132: Fly Ash, Silica Fume, Slag, and Natural Pozzolans and Natural Pozzolans in Concrete - Proceedings Fourth Interna", 1992This paper presents test data on the development of the microstructural porperties of concrete containing 50% replacement of cement by ground granulated blast furnace slag of varying fineness. The following characteristics and properties were investigated: pore structure; hydration and rate of heat evolution; microstructure by scanning electron ...
