Utilization of copper slag in cement and concrete ... Copper slag is a byproduct obtained during matte smelting and refining of copper. The common management options for copper slag are recycling, recovering of metal, production of value added products such as abrasive tools, roofing granules, cutting tools, abrasive, tiles, glass, roadbase construction, railroad ballast, asphalt pavements.
Mar 17, 2018· The objective of this project is to study the copper slag as replacement of fine aggregate for 0%, 20%, 40%.

The use of separately ground blastfurnace slag, added at the mixer as a replacement for a portion of the Portland cement, has gained increasing acceptance in recent years. The effects of partial replacement of Portland cement with ground slag on the properties of hardened concrete have been extensively investigated and reported.
cementitious material source and replacement rate on shrinkage of bridge deck concrete. Two sources of Class C fly ash, two sources of Class F fly ash, and one source of slag cement were used and combined in various replacement rates with portland cement to develop the sixteen mixtures for this study.
Slag Cement Benefits and Use in Concrete Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. Get Price; Slag Cement Association > About Slag Cement > IS01. Slag cement, or ground granulated blastfurnace slag (GGBFS), has been used in concrete projects in the United States for over .
Most mineral wool produced in the United States today is produced from slag or a mixture of slag and rock. Most of the slag used by the industry is generated by integrated iron and steel plants as a blast furnace byproduct from pig iron production. Other sources of slag include the copper, lead, and phosphate industries.
Legislation intended to stimulate recycling efforts is in force in a number of states and is being debated in others. The state of the practice in the use of waste materials in highway construction in the United States and the perfor mance of the selected waste products are discussed.
The effect of ground copper slag (GCS) on the strength and fracture of cementbased materials is studied. Up to 15% by mass of GCS was used as a portland cement replacement. The strength and fracture toughness of concrete samples were studied using closedloop controlled compression and threepoint bending fracture tests.
The development of more efficient processing techniques in the late1800s allowed the mining of lowergrade copper ores from huge openpit mines in the western United States. Today, the United States and Chile are the world's top two copper producing countries, followed by Russia, Canada, and China.

The primary applications for steel slag in the United States are its use as a granular base or as an aggregate material in construction applications. Disposal. While most of the furnace slag is recycled for use as an aggregate, excess steel slag from other operations (raker, ladle, clean out, or pit slag) is usually sent to landfills for disposal.

about 104 for some GGBFS. Aircooled iron slag and steel slag are used primarily as aggregates in concrete (aircooled iron slag only), asphaltic paving, fill, and road bases; both slag types also can be used as a feed for cement kilns. Almost all GGBFS is used as a partial substitute for portland cement in concrete mixes or in blended cements.
GGBS Proportions. On its own, ground granulated blast furnace slag (GGBS) hardens very slowly and, for use in concrete, it needs to be activated by combining it with Portland cement. A typical combination is 50% GGBS with 50% Portland cement, [4]but percentages of GGBS anywhere between 20 and 80 .
addition copper slag has been excluded from the listed hazardous waste category of the United States Environmental Protection. Copper Slag is a glassy granular material with high specific gravity. Particle sizes are of the order of sand and have a potential for use as fine aggregate in concrete. Sieve analysis of copper slag is tabulated in Table4. Table4 Properties Observed
