Abstract: s. Using industrial waste residue as concrete mineral admixture has become a direction of the development of the green concrete. Nickel slag is mainly introduced, and the chemical composition and preparation of nickel slag powder, and study its physical properties, activity, volume stability and mechanical properties.
The raw materials for the test include nickel slag, cement, a solid alkali activator, standard sand, water, citric acid, and water reducer. The particle size of the undisturbed water-quenching nickel slag used in the test was about 3-4 mm. The Blaine surface area and specific gravity are .
Jun 15, 2017· Nickel slag abrasive material is a grit that is used in a blast cleaning process prepared by selective screening. Nickel slag abrasive grit is available in various grades and sizes and has a Moh's hardness ranging from 6.5 to 7; which provides improved cutting relative to conventional industrial and silica sand abrasives.
A copper-nickel slag-based alkali-activated cementing material (CNSCM) for backfilling was prepared using copper-nickel slag as a raw material and sodium silicate (SS) as an activating agent.
Nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high
Alkali-activated copper and nickel slag cementitious materials (ACNCMs) are composite cementitious materials with CNS (copper and nickel slag) as the main materials and GGBFS (ground-granulated blast-furnace slag) as a mineral admixture. In this paper, the activity indexes of CNS with different grinding times were studied using CNS to replace a portion of cement.
Jul 20, 2017· This study applied high-volume electric furnace nickel slag (FS), phosphorous slag (PS) and a mixture of the two (FP) to massive concrete, and using fly ash (FA) as the control admixture, investigated the effects of FS and PS on the hydration and hardening process of the cementitious materials, the mechanical properties and the durability of the concrete. Two curing conditions were .
The fine slag powder is used as an admixture in cement and concrete production. It can replace 20%-30% of cement consumption in concrete and cement products for various purposes, which not only conforms to the development trend of energy saving and emission reduction in the building materials industry, but also achieves the goal of reusing ...
Apr 12, 2013· The heavy metal leaching is mostly related to the stainless steel slag since it contains a higher amount of chromium (Cr) and nickel (Ni) than the ordinary steelmaking slag. In Germany steel slag processed to aggregates for road construction and hydraulic structures have to be analyzed by leaching tests twice a year.
The invention provides a high-strength concrete of aggregate nickel-doped slag. The high-strength concrete comprises a binding material and aggregate, wherein the binding material comprises cement, mineral powder and coal ash; the aggregate comprises yellow sand, pebble and nickel slag; in every cubic meter of the concrete, the mass of cement is 365-405kg, the mass of mineral powder is 68 ...
Steel slag, water slag, manganese slag, nickel-iron and coal slag can be used as admixtures for concrete mixing station after grinding. The Main Uses: 1) Direct mixing of slag and Portland cement in a certain proportion in cement production can improve the performance of cement and reduce production costs and energy consumption.
s. Using industrial waste residue as concrete mineral admixture has become a direction of the development of the green concrete. Nickel slag is mainly introduced, and the chemical composition and preparation of nickel slag powder, and study its physical properties, activity, volume stability and mechanical properties. According to nickel slag powder admixture amount of replacing cement ...
Ground granulated blast furnace slag is produced by pulverizing granulated blast furnace slag produced by blast furnaces as a by-product of the iron-making process. This hydraulic admixture is popular for use as raw material for Portland blast furnace slag cement, admixture for .
In this study, the coarse aggregates used were local aggregates and the nickel slag used came from PT. Vale Soroako. Viscosity modifying admixture used is viscocrete 8050 PT.
Cominco, a Canadian firm, operated the mine under the Glenbrook Nickel name from 1989 to 1998. In January 2003, Green Diamond bought another 600-acre chunk — this time the smelter and slag property below the mountain — for $750,000, positioning the company for a cost-saving consolidation.

Without a chemical admixture, the compressive strength of concrete after 28 days is fc' 30 MPa and the specific surface area is 4360 cm 2 /gr. The compressive strength of high-magnesium nickel slag powder is capable of replacing cement by 20% without altering properties of concrete.
Figure 3 TG, DTG and DSC map of blast furnace of copper-nickel slag hydration of 28d . ... that along with the increase of copper slag admixture, the concrete strength decreased from these figures4-6, but the drop range is small. As the strength increases, the brittleness of concrete increases. When copper slag content is 5%,
Globe Metal has Ni slag for sale. The material contains 15-20% Nickel, and is located in Canada. Globe Metal currently has a supply of 19,500 lbs. Please contact Josh to receive more details about the material. Learn more about metals that we recycle.
vertical slag mill is typically designed to deal with industrial waste residues generated by the blast-furnace ironmaking. Due to its high physical and chemical activity, and potential hydraulicity, the slag has been widely as admixture matters in the cement industry. And the slag can replace the cement in the concrete to improve the quality and durability of the concrete.
George C. Wang, in The Utilization of Slag in Civil Infrastructure Construction, 2016. 14.4.1.1 Materials. Two nickel slags, based on different cooling processes (ie, AC slag and emergency pit (EP) slag), were selected for this study.The laboratory work consisted of sample preparation, crushing and blending of large, bulk samples of AC nickel slag.
Mar 05, 2020· Alkali-activated copper and nickel slag cementitious materials (ACNCMs) are composite cementitious materials with CNS (copper and nickel slag) as the main materials and GGBFS (ground-granulated blast-furnace slag) as a mineral admixture.
A copper-nickel slag-based alkali-activated cementing material (CNSCM) for backfilling was prepared using copper-nickel slag as a raw material and sodium silicate (SS) as an activating agent. The effects of SS content (6%, 8%, and 10%) and curing humidity on the compressive strength of CNSCM were investigated using an electronic universal testing machine.
Nickel slag is a solid waste produced from smelting ferronickel alloy. Ferronickel alloy is mainly used for stainless steel production, so nickel slag is also called stainless steel slag or nickel iron slag. Nickel slag powder can be used as mineral admixture for concrete, which .
