GGBS

GGBS Applications

Blast Furnace Slag is a by-product from the manufacturing of steel in a blast furnace. Initially in its molten form, it is diverted to a granulator where it is quenched with water and rapidly cooled to form glassy, non-metallic granules which are silicates and aluminosilicates of calcium. These granules are dried to produce Granulated Blast Furnace Slag (GBFS) and then ground to a suitable fineness to produce Ground Granulated Blast Furnace Slag (GGBFS). When used as a cementitious material in concrete, GGBFS enhances long-term performance and durability characteristics while reducing life-cycle and maintenance costs. We source GGBFS from JSW Steel Ltd. - which is one of the largest steel producers in India..


MIOR GGBS Quality

At MIOR, GGBS is ground to a controlled fineness through Vertical Roller Mills with the latest technology and quality control systems to produce GGBFS. The grinding process takes account of mean particle size, grading (particle size distribution) and particle shape, thus giving quality-assured material which is consistent, predictable and suitable for varied applications.


MIOR GGBS Benefits

In concrete, MIOR GGBFS may be proportioned from 20% to 80% depending on the application. It is substituted for Portland cement on a one-to-one basis by mass. The proportion of MIOR GGBFS used is usually dictated by requirements for strength, durability, time of set, heat generation, or the resistance of the concrete mixture to alkali silica reaction (ASR) and sulphate attack. Water demand for any given slump generally reduces by 5% upon addition of MIOR GGBFS. Some key advantages of MIOR GGBFS in concrete include high compressive strength, high flexural strength, low permeability and chemical attacks, low heat of hydration and thermal cracking in mass concrete, alkali silica reaction and sulphate attack mitigation, improved workability and finishing characteristics. The service life of structures using MIOR GGBFS is enhanced by more than 100% on account of superior durability of concrete. GGBFS use in concrete qualifies for credit under the U.S. Green Building Council's popular LEED™ rating system for sustainable construction..
