Granulated blast furnace slag (GBFS) is widely used in cement and concrete industries due to its excellent hydration properties. However, there is a huge capacity gap between the steel industry and the cement industry, and hence, the supply of GBFS can hardly meet the demand. At present, few studies have focused on the preparation of cementitious …

Together, the projects are expected to reduce the equivalent of more than 14 million metric tons of …
The good news is that the cement industry is poised to sustain its gross margin expansion, primarily driven by higher cement prices and significantly reduced fuel costs, despite anticipated weak global demand.
Muffle furnace is used in the processing of materials at high temperatures. Know more about Muffle Furnace uses, price, and manufacturers.
The staggering production volumes of cement, steel and chemicals are at the core of the calamitous climate problem posed by heavy industry. Over one-quarter of global emissions result from industrial processes — more than from all forms of transportation combined — and that figure is driven mainly by these three materials.
Appropriate concrete quality (blast-furnace cement and low lime content) and professional construction are important to prevent corrosion and leaks in the tank wall. Concrete digesters can be built partially or completely in the ground. Steel digesters are built on concrete foundations above ground.
One such by-product from iron smelting industry is iron slag, which is generated from blast-furnaces while extracting iron. This blast furnace slag is used to make a cementitious material by grinding it into fine powder, known as Ground Granulated Blast Furnace Slag (GGBS).
Normally, SS is dried using the waste heat from the cement kiln. It is placed in the main furnace of the cement kiln and burned as a fuel, or it is. gasified beforehand and the gas produced is ...
The cement and concrete industry (CCI), which is integral to global infrastructure development, is therefore confronted with a growing need to decarbonize its operations and products, as well as ...
Abstract. This paper deals with the use of industrial by-products from electric arc furnace (EAF) granulated slag for the partial replacement of natural aggregates commonly used to manufacture concrete. Three different gradings of EAF granulated slag were considered. The rheological and mechanical properties of concrete manufactured …
The method, which the researchers say is "an absolute miracle", uses the electrically-powered arc furnaces used for steel recycling to simultaneously recycle cement, the carbon-hungry component of concrete.
These steel producers anticipate that by 2040–2050, all European Union blast furnaces will close to meet social pressures to decarbonize the steel industry. DRI shaft furnace ironmaking allows a large and immediate reduction in GHG emissions using natural gas in place of coal.
Utilisation of Alternative Fuels and Raw Materials (AFR) in cement industry, therefore, helps in reduction in carbon footprint, increased sustainability, avoiding consumption of fossil fuel and its …
A continuous rotary furnace is operated by Nova Pb [8]. It is the last remaining of three plants which utilized modified cement kilns to dry, and smelt secondary materials on a continuous high throughput basis. The furnace utilizes the same Na 2 S–FeS slag chemistry as conventional furnaces. Newer rotary furnace installations combine the …
Ground granulated blast furnace slag (GGBFS) or slag cement is a granular by-product material produced from iron blast furnaces of the iron making industry. Blast furnace slag (BFS) is formed when a limestone or dolomite flux, iron ore or iron pallets, and coke are melted together.
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.
Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the ...
Better technology and process improvements are needed to improve energy efficiency, throughput, and melt loss within the secondary aluminum industry. One of the first steps is to understand our current state to provide a basis to know where work is needed. This article provides a review of current aluminum melting and holding …
Laying the foundation for a zero-carbon cement industry | McKinsey. As a key component of concrete, cement is an integral part of our everyday lives. In fact, it is the second-most-consumed product globally after potable water, and it is used in almost everything we build—from houses and cityscapes to dikes and dams.
One of the common methods used in waste heat recovery for the cement industry is a waste heat boiler. A waste heat boiler is a boiler that utilizes medium to high-temperature exhaust gases to ...
Zero-emission 'electric cement' is an 'absolute miracle'. The new process involves arc furnaces and molten steel. Researchers hope to soon produce 66 tons of 'electric concrete' within ...
improving the thermal efficiency of the energy-intensive process of cement manufacturing. This chapter discusses the role of preheaters and precalciners in improved pyroprocessing and related material, operation, and environment benefits to …
Electric arc furnace scrap steel operators are probably getting annoyed at all the cement nerds that want to play with their furnaces and waste.
Semantic Scholar extracted view of "Synergistic utilization of blast furnace slag with other industrial solid wastes in cement and concrete industry: synergistic mechanisms, applications, and challenges" by Qingsen Zeng et al.
For sustainable development in the construction industry, steel slag has been used as a substitute for cement in concrete. Steel slag is a byproduct from steel making industry [ 1] characterized by variable chemical components and low cementitious properties.
The cement industry is considered energy-intensive, because its energy needs to achieve high temperatures. Traditionally, it used fossil fuels such as coal, fuel oil, and petroleum coke. The co-processing of industrial waste is an attempt to reduce the use of such fuels. In this process, waste is added to raw materials by replacing, in part, fuels …
