Sustainable Construction. In Singapore, copper slag is largely used as abrasive for the removal of rust and marine deposits that have accumulated on ships. Spent copper slag originates from raw copper slag that has been spent of its abrasive property after using it to remove rust and marine deposit from ships.

** We do have a slightly less aggressive water cooled copper slag also available. Independent studies have shown it to be the fastest cutting slag abrasive. Enviromentally friendly. Approved for recycling in Portland cement. Best abrasive to use when ranked on cutting speed and cost per sq. ft., according to independent NIOSH tests.

Oct 20, 2016· It is used to fireproof steel and used in high temperature and blast applications. 7. Ability to Consume and Recycle Waste. Many industrial wastes can be recycled as a substitute for cement or aggregate. This includes fly ash, slag also known as GGBFS or ground granulated blastfurnaces slag, waste glass, and even ground vehicle tires in concrete.

Waste copper slag is a refractory material with high iron content, but it is difficult to recovery iron minerals from the slag because the iron mainly occurs in fayalite. A new technology of coalbased direct reductionmagnetic separation process was developed to recover iron from the slag assaying % Fetotal and % Cu.

Copper slag can be used as fine aggregate in concrete describing the strength, setting time and durability of concrete mixtures made with copper slag [16, 17]. Also, up to 15% by weight of copper slag was used as Portland cement replacement together with up to % of hydrated lime as an activator to pozolanic reactions and the results

A series of concrete mixtures were cast in cubic moulds of nominal size 100 mm with different proportions of pulverized copper slag ranging from 0,, 5, 10 and 15% respectively replacing Portland cement. Activation of the pozzolanic reaction of the pulverized copper slag was done using % hydrated lime (Ca(OH) 2) by weight of The PC.

Jan 16, 2017· Partial replacement of Fine aggreggate by Copper Slag and Cement by Fly Ash 1. 1 Replacement Of Fine Aggregate By Copper Slag And Cement By Fly Ash Ammini College Of Engineering, Mankara, Palakkad 1. INTRODUCTION GENERAL Concrete is the man made material widely used for construction purposes.

Abstract: Chemical composition of copper slag presents a high Fe, Si and Al oxide content what makes it a pozzolanic material. Thus, it is possible to use it as a partial replacement for sand and after triturating it into very small particles as a replacement for cement. After a chemical, physical, mineralogical,...

Comparison Of Engineering Properties Between Pure Copper Slag Brick And Spent Copper Slag Brick Proceedings of TheIRES 3rd International Conference, Dubai, UAE, 4th July 2015, ISBN: 9 replacement in making cementsand brick.

Copper Slag is used to increase the strength of concrete and reduces the environmental pollution, space problem and also reduces the cost of concrete. Copper slag has also gained popularity in the building industry for use as a fill material. Contractors may also use copper slag in place of sand during concrete construction. Copper slag can also be

This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering.

ordinary Portland cement. The use of copper slag reduces the early age strength (1 day) while increasing it beyond 7 days [4]. The use of ground copper slag up to 15% by mass as a Portland cement replacement increased the strength significantly [5]. The addition of copper slag to cement increasedits initial and final setting times [6].

Aug 30, 2001· The optimum copper slag and cement bypass dust to be used is 5%. In addition, it was determined that using cement bypass dust as an activating material will work better than using lime. Additional studies should investigate the strength and durability when copper slag and cement bypass dust are used in concrete mixes.

Copper slag blasting edia/grit is manufactured of the granulated slag of copper refineries, and used for blastcleaning of metal surface. Copper slag has also gained popularity in the building industry for use as a .

While fly ash and copper slag are used for partial replacement of cement and fine aggregate, respectively, defined quantities of steel and polypropylene fibres were added to the mixes.

The copper slag obtained may exhibit pozzolanic activity and may therefore be used in the manufacture of additioncontaining cements. In this paper the effect of the incorporation of the copper slag in cement is measured. Blends of copper slag with Portland cement generally possess properties equivalent to Portland cement containing fly ash, but very different to the silica fume incorporation.
