Distribution Statement Ground granulated blast furnace slag, concrete mixes, slag, GGBFS, high range water reducer, HRWR, portland cement, Hiraskar and Chetan Patil Abstract-The Iron industries produce a huge quantity of blast furnace slag as by–product, which is a non–biodegradable waste material from that only a small percentage of it is used by cement industries to manufacture cement. Use of activated slag resulted in a remarkable increase in strength vis-à-vis slag cement. While this is a new method of use in this country, the cementitious material is not new: it is an improved Portland blast-furnace slag cement. Go´meza, K.K. Production of Portland blast-furnace slag cement began in 1910, and the Japanese national standard for Portland blast-furnace slag cement (JES 29) was formulated in 1926.some of the study has been done in past which summa-rized as: 1. 2, 3)History of Portland Blast Furnace Slag Cement 3.1 Birth of portland blast furnace slag cement As mentioned earlier, PBFSC was developed in 1910—nine years after the government-managed Yawata Works was put into op-eration. The activation of blast-furnace slag with alkaline liquids (e.g., NaOH or water glass) to produce alkali-activated slag cement The blast furnace slag cement is used in the world in order to increase the strength of the concrete and reduce the costs. This specification covers three strength grades of finely ground granulated blast-furnace slag (Grades 80, 100, and 120) for use as a cementitious material in concrete and mortars. Ground granulated blast-furnace slag (GGBFS) has latent hydraulic properties that could be activated using suitable activators [4]. The total content of blended materials could increase if two additives were used. GGBS Concrete GGBS Proportions On its own, ground granulated blast furnace slag (GGBS) hardens very slowly and, for use in concrete, it needs to be activated by combining it with Portland cement. 4.2.3 Portland Blast Furnace Cement. to metallurgical slag produced in modern blast furnaces (i.e. When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace.The molten slag must first be separated from the molten iron. 5.3.1 For packing of Ground granulated blast furnace slag in bulk cement terminal weighment of hourly check of mass of drums also shall be done in addition to weighment of bags mentioned in para 5.3 above. This specification covers three strength grades of finely ground granulated blast-furnace slag (Grades 80, 100, and 120) for use as a cementitious material in concrete and mortars. Table 4 shows mixture proportions of concrete for freeze and thaw testing. Tata Steel IBMD is one of the leading suppliers of GGBS and the product has been used in construction of many iconic structures in India. Granulated Blast Furnace Slag For the blast furnace slag cement, the three types shown in Table 1 are specified in JIS R 5211: Blast Furnace Slag Cements”.

Slag cement, or ground granulated blast furnace slag (GGBFS), has been incorporated into concrete projects in the U.S. for over a century to improve durability and reduce life cycle costs. Nippon Steel & Sumitomo Metal Corporation By reducing the limestone and fuel used for the production of cement, the CO₂ generation is reduced by 320 Kg per 1 ton of cement. blast-furnace slag and fly ash has been reported in many research works [5,6]. Use of Blast Furnace Slag Aggregate in Concrete K.G. The blast-furnace slag is crushed and screened to provide blast-furnace slag particles having particles with a predominant size of up to a maximum diameter of substantially 2" or less. Slag was processed by 28 companies servicing active iron and steel facilities or reprocessing old slag piles at about 129 processing plants (including some iron and steel plants with more than one slag-processing facility) in 33 States, including facilities that import and grind unground slag to sell as ground granulated blast furnace slag (GGBFS). Abstract. The glass content, which is a significant factor to evaluate the performance of BFS as a replacement material for Portland cement, was investigated using the X‐ray diffraction method. blast furnace slag is separately ground and then mixed with the cement. blast-furnace slag cement.
