This specification covers three grades of finely ground granulated blast-furnace slag for use as a cementitious material in concrete and mortar. The material described in this specification can be used 1) for blending with portland cement to produce a cement meeting the requirements of Specification C 595 or 2) as a separate ingredient in ...
Ground Granulated Blast Furnace Slag plays a vital role in making stronger and durable concrete structures and is among the most sustainable building materials in India. Tata Steel GGBS has been awarded the Green Pro Certification for being a sustainable building material.
Granulated Blast Furnace Slag is obtained by rapidly chilling (quenching) the molten ash from the furnace with the help of water. During this process, the slag gets fragmented and transformed into amorphous granules (glass), meeting the requirement of IS 12089:1987 (manufacturing specification for granulated slag used in Portland Slag Cement).
Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties.
The slag obtained from different sources can be utilized as supplementary raw materials in different construction applications such as concrete aggregate, hot-mix asphalt and granular materials as investigated by various researchers [3-6]. The industrial application of granulated blast furnace slag is due to their enormous power of activation.
In 1880, mass slag concrete is reported to have been used in Pennsylvania; and in 1897 reinforced slag concrete was used in the construction of the Harrison Estate Building, Philadelphia, Pa. The earliest recorded application of slag as aggregate for reinforced bridge construction of considerable magnitude was its use in building the
Slag Products Ground-Granulated Blast-Furnace Slag (GGBFS) is used to make durable concrete structures in combination with ordinary Portland cement and/or other pozzolanic materials. It has been widely used in cement /construction industries for its superiority in concrete durability, extending the lifespan of building significantly.
While substitution of ground granulated blast-furnace slag for up to 70% of the portland cement in a mix has been used, there appears to be an optimum substitution percentage that produces the greatest 28-day strength. This is typically 50% of the total cementitious material but depends on the grade of ground granulated blast-furnace slag used.
