Concrete with Copper Slag Fine Aggregate.
Journal of the Society of Materials Science, Japan, 2000 Copper slag is a by-product yielded from a copper refinery. The annual amount of copper slag in Japan is two million tons. The copper slag has been used for cement material, sand blasting, reclamation and so on. However, most of the copper slag is stacked high as waste since the production exceeds demand. This study on the application of copper slag as

Hydration Behavior of Blast Furnace Slag Activated by Na2SO4 and Fineness of Slag
Resources Processing, 2006 The effect of alkali activator and fineness of slag on the physical properties of blast furnace slag cement was investigated. Na2SO4 was used as an alkali activator in this study. Blast furnace slag cement was prepared from mixture of blast furnace slag, ordinary Portland cement, and anhydride gypsum. The fluidity and the compressive strength according

Strength and durability studies on slag cement concrete made with copper slag as fine aggregates
Materials Today: Proceedings, 2021 Abstract The current investigation is an attempt to perform the strength and durability studies on slag cement concrete prepared by using copper slag (CS) as a fractional/full replacement for natural fine aggregates (FNA). Tests were performed for compressive strength, split tensile strength, acid attack, sulfate attack, water absorption, and voids ...
