5. Slag Cement Manufacturing Slag Cement - BFSC Blast Furnace Slag, a waste product of Steel Industry has 'hydraulic properties' of hardening like Cement clinker and hence serves as an ideal 'blending' material so much so that slag and clinker can be mixed in proportions of 60 : 40 and ground with gypsum to make slag cement. Thus a …
2) The addition of blast furnace slag to expansive soils reduces swelling, plasticity, and clay content which mitigates heave. 3) Blast furnace slag can be used as an alternative binder to cement in road construction applications due to its slow setting properties, improving workability during application and long-term strength development ...
Heidelberg Materials Slag Cement and portland cement exhibit higher strengths (flexural and compressive), reduced permeability and increased durability compared to portland …
The lighter color of slag cement concrete (compared with concrete made with other cementitious materials - see photo) is generally considered to be a positive benefit, as it not only improves the aesthetic look of concrete, but also increases concrete's reflectivity (albedo) which provides greater mitigation of the "urban heat island effect ...

Study on the Preparation of High Performance Concrete using Steel Slag and Iron Ore Tailings ... Similar to cement, Steel slag can react with water, producing Ca(OH)2, C-S-A-H gel, C-A-H crystal, C-S-H gel, and so on [13-15]. Thus, SS is considered as a supplemental cementitious material [16-19]. At present, SS is mainly used as subgrade ...
In concrete, PLC also performs well with slag or fly ash at normal replacement levels. In many cases, Type IL+SCM perform better at early age than Type I+SCM, due to …
Replacing a portion of portland cement with slag cement – typically from 30% to 50% – significantly lowers the environmental impact of concrete. Slag cement requires nearly 90% less energy to produce than portland cement. According to the Slag Cement Association, substituting 50% slag cement for portland cement reduces greenhouse …
NewCem® Slag Cement is a finely ground, granulated blast furnace slag (GGBFS) available to blend with conventional Portland cement to deliver a strong, high-quality, durable concrete. Concrete production utilizing NewCem consumes less energy and offers improved efficiency and building performance.

How is Portland Slag Cement Made? The manufacturing process of Portland Slag Cement (PSC) involves the following steps: Obtaining Granulated Blast Furnace Slag: Granulated blast furnace slag is obtained as a by-product in the iron and steel industry.During the production of iron, blast furnaces produce molten slag, which is then quenched rapidly …
Today, cement and concrete are some of the most consumed materials after water throughout the whole world. About 4.1 billion tons of cement are fabricated annually (half a ton per person) and half of this amount is produced by China [5].In addition, >1 m 3 of concrete per person is produced with Portland cement each year [6].Today, …
This development resulted in the first commercial use of slag-lime cements in Germany in 1865. In France, these slag cements were used as early as 1889 to build the Paris …
3. Ground granulated blast furnace slag (GGBS) is the by product of manufacturing of pig iron. Iron ore, coke and lime stone are fed into the furnace and the resulting molten slag floats above the molten iron at a temperature of about 1500oC to 1600oC. The molten slag has composition close to chemical composition of Portland …
