As slag is generated at high temperature as a liquid in the blast furnace during iron production and subsequently quenched, its composition is essentially that of an overcharge-balanced calcium aluminosilicate framework – i.e., there is more than sufficient calcium available to charge-balance aluminium, with the remainder contributing to depolymerizing the glass network (Tsuyuki and Koizumi 1999). 0000062424 00000 n 0000006552 00000 n Ground granulated blast-furnace slag, when used in general purpose concrete in The liquid nickel slag is transported by rail to a stockpile area where it is discharged and allowed to cool and solidify under ambient conditions (Fig. Fig. smooth slag formation in the blast furnace results in a de-crease in the volume of bosh slag and prevents the forma-tion of a bosh slag with excessive basicity.1–3)At normal blast furnace operation, the tuyere slag, formed by the ash content in fuels combusted in front … Typically, the proper basic-oxygen furnace charge consists of approximately 10–20% of steel scrap and 80–90% of molten iron [ 1, 3 If used as cement bound base course, reduced cement content can be expected to achieve the required strength. Fragmented sized and crushed and screened to a wide range of gradations for highway construction uses (B). Materials used in two rural test road sections. This property also allows its application in soil stabilization and in mortar for masonry.

Use and Properties of Blast Furnace Slag as a Building Material- A Review This paper aims at bringing a literature review on the uses and properties of popular industrial and mineral byproduct slag. Suction cups were used to collect the seepage water in the middle and the edge zone of both sections with either EAF slag and natural aggregate in the road base as well as 5 m (16.4 ft.) to the side of the test road. 1992, Richardson et al. 0000007616 00000 n 0000091506 00000 n 20 cm (67%) EAF and ladle slags (expansion rate of mixture 1.18%), EAF slag–3 month aging with expansion rate of 0.93%; ladle slag–3 month aging with expansion rate of 3.34%. (2011). This paper reviews the production, processing, and characteristics of steel slag, and its use as a cementing component in different cementing systems. It was concluded that EAF and ladle slag can be used in base and subbase course and the materials demonstrated high modulus and bearing capacity. 0000016025 00000 n Data from Bialucha, R., Nicoll, R., & Wetzel, T.
