Blast-furnace slag cements are a type of hydraulic binding material that is produced by intergrinding granulated blast-furnace slag and a specified amount of gypsum or anhydrite. The granulated blast-furnace slag is a by-product of iron production and is quenched with water or steam to form a glassy, granular product. This slag is then finely ground to achieve the desired fineness, which contributes to the cement's unique properties and performance characteristics.
In blast-furnace slag cements, the granulated slag acts as a supplementary cementitious material, enhancing the strength, durability, and workability of the cementitious system. This type of cement is known for its ability to reduce heat of hydration, improve sulfate resistance, and enhance long-term durability. Blast-furnace slag cements are often used in concrete construction applications where high performance and sustainability are desired, making them a popular choice in the construction market.
During the production process of blast-furnace slag cements, the primary raw material used is granulated blast furnace slag, obtained as a byproduct in the steelmaking market. This slag is then ground into a fine powder, typically similar in fineness to Portland cement. The finely ground slag is blended with Portland cement clinker in specific proportions to create the desired characteristics in the final product. The blending of slag with clinker enhances the cement’s properties, such as improved workability, reduced heat evolution during hydration, and increased resistance to sulfate and chloride attacks.
Once the slag and clinker are thoroughly mixed, the resulting mixture is finely ground to achieve the desired particle size distribution, ensuring optimal performance of the cement. The final product, blast-furnace slag cement, offers several advantages over traditional Portland cement, making it a preferred choice in various construction applications. The production process of blast-furnace slag cements requires precision and quality control at every stage to deliver a superior product that meets market standards and customer expectations.
Blast-furnace slag cements offer several distinct advantages in construction applications. One significant benefit is their enhanced durability and resistance to chemical attacks, which can help increase the lifespan of concrete structures.
