What is a smoked granulated slag with a blast furnace?
The by -product of the production process, when steel and iron are melted, granulated granulated brushes are most often used in cement products. Also known as GGBS or GGBFS, dry powder is produced by grinding a product that results in soaked melted iron slag. The term is applied to the waste produced during the iron melting process. Of these two products, the most commonly used cement is Portland Blast Furnace (PBFC), which contains approximately 30% of the slag furnace. The alternative product is known as a cement with a high black oven (HSBFC) and contains a higher concentration of a blast furnace, usually up to 70%. Both products are used to produce doses of finished mixed concrete for structural applications. In addition to the apparent environmental sustainability, which is to be obtained from using the secondary waste product instead of the primary source material. Incorporation of the blast furnace helps prevent the penetration of chloride into the concrete structure.Ingress chloride can lead to advanced corrosion of steel reinforcement members - a state commonly known as concrete cancer .
Financially, the use of a blast furnace as an admixture in concrete is generally cheaper than standard OPC mixtures. The product is also resistant to sulphate attack and alkaline-Silica reactions that can significantly reduce the life of the concrete structure. Concrete can also be aesthetically more pleasant due to the white appearance of a cured product compared to the matt -gray color provided by a conventional OPC mixture.
Ground granulated slag with a blast furnace in finished mixed concrete means that the product requires a longer curing time-time degree needed to ensure that the concrete is evaluated by the OPC products. Although it may be an advantage when considering the reduced risk of the need for colds, it may become disadvantageous when a tight time schedule of concrete pouring is planned.
Cold joints occur when parts of concrete walls or similar structures are left to fully cure before it can be poured by the navigable section. As a result, the new section will not be able to connect correctly to the existing section due to a smooth surface. To overcome this, it is necessary to break the existing surface back into the rough surface. This allows the new section to connect with the previously poured section. A longer curing time provided by the inclusion of chips on a ground granulated furnace means that the existing surface is prolonged for a longer period of time.
