This might be difficult, as testing coarse aggregates for ferrous sulfides is not a requirement for meeting ASTM C33, "Standard Specifications for Aggregates." Nor is this particular reaction identified in ACI 221's Table 1.1, which shows properties of concrete influenced by aggregate properties.
This article presents the results of an experimental research dealing with the use of steel slag as a partial substitute for natural aggregates in the production of concrete composite. Comparative mixture based on natural aggregates was prepared from the fractions of 0/4, 4/8 and 8/16 mm, which were represented in the volume ratio of 40:30:30.
aggregate in concrete has no negative effects on the short term properties of hardened concrete. So Steel slag meets the requirements to be used in concrete mixes. Compressive strength, flexural strength and splitting tensile strength for steel slagaggregates concrete were similar to conventional concrete.
Oct 09, 2012· Cement substitutes are distinguished from aggregate substitutes, such as ground scrap rubber and ground glass, and concrete additives, such as air-entrapment agents and plasticizers. Inspectors will not be able to visually identify concrete that has had substitutes for concrete incorporated into the mix.
were compared with conventional concrete. Thus the use of iron slag in concrete could enhance the strength in concrete. Keywords: Natural coarse aggregate, Iron slag, Iron slag aggregate, concrete, cement 1. Introduction Iron slag is a by-product of the iron and steel making process. Steel cannot be prepared in the Basic Oxygen

EP1589121(A) discloses a lithium battery recycling process using a shaft furnace, producing a lithium-bearing slag that is used as a gravel substitute in concrete. The environmental stability of concrete containing 30% of such slag is tested by percolating acidified water through the comminuted concrete.
Peerless manufacturers low cost, free ﬂowing, oil and moisture free, cold worked Iron and Steel aggregates for ballast, high density concrete, grout, and other applications. The following properties of our cold worked steel aggregate make it superior to cast steel shot for all high density concrete …
Heavyweight concrete is widely used for radiation shielding of nuclear reactors and other structures that require radiation impermeability. Aggregates play here an important role – while hematite and other iron ores are commonly used for the purpose. However, little information on properties of hematite-containing concrete other than radiation
The physical and chemical properties of copper slag were investigated. Copper slag, in amounts of 20, 40, 60, 80, and 100 percent, was substituted for fine aggregate in cement mortar and concrete. The fineness modulus of the combination of copper slag and fine aggregate was roughly 2.6, the optimum fineness modulus for concrete mix design.
