Iron and steel slag are widespread in Nigeria because the industries producing these by-products are found in the north, south, west and east of Nigeria (Elijah, 2013). Hence, iron and steel slag as alternative substitute to granite aggregate in concrete production is readily and locally available. Previous studies on the
Study on Utilization of Iron Ore Tailings as Fine Aggregates and GGBS as Partial Substitute in Concrete. Shwetha R A. Assistant professor, Civil Engg, KNSIT, Karnataka, India. Abstract -In this study, M20 grade of concrete was produced by complete replacing fine aggregate by Iron ore tailings, and GGBS as partial substitute to cement at 10%, 20%, 30% and 40%.
Nov 19, 2020· Iron filings were utilized as incompletely substitute of cement in concrete. Results attained revealed that there is an increment in the compressive strength and indirect tensile strength of
This research found that concrete using iron ore as an aggregate has a compressive strength higher than normal concrete that is equal to 38.90Mpa assuming greater size of iron ore as aggregate, the higher the Fe content, the size of escaped iron ore mesh aggregate 20, mesh 20 , mesh 5, 8-10 mesh and 10-12 mm mesh respectively 47,460%, 38,346%
products which can be utilized as fine aggregates in concrete. One such byproduct is iron slag (IS). During the production of iron in blast furnace, blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace.
The iron aggregate concrete floor is a concrete floor topping specifically designed for industrial facilities, warehouses, distribution centers, manufacturing plants or logistics facilities. The iron aggregate filled concrete floor protects from heavy, direct impacts made to the concrete floor or from rubbing, scraping or erosion.
Use of Iron ore dust as an alternative to normal aggregates in concrete M. Nadeem et al [3] draws serious attention of researchers and investigators. And large quantity of construction waste as well as demolition waste such as paving blocks, tiles, timber, plastic, cardboards, metals and papers etc..
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.
The American Concrete Institute. Founded in 1904 and headquartered in Farmington Hills, Michigan, USA, the American Concrete Institute is a leading authority and resource worldwide for the development, dissemination, and adoption of its consensus-based standards, technical resources, educational programs, and proven expertise for individuals and organizations involved in concrete design
Iron Slag Sand: IS 383 permits upto 25% replacement in RCC and 50% in PCC/ PQC and 100% in Lean Concrete; Copper Slag Sand : Same as above; Fly Ash: Upto 25% replacement in Lean Concrete; Recycled Crushed Concrete.
This study aims to determine the characteristics of the aggregate and to analyze the strength of the concrete mixture using Iron Slag as a substitute for fine aggregate. This research is an experimental study which was conducted in the Laboratory of Concrete and Structural Materials, Bosowa University.
Nov 01, 2018· Slag preparation. A ferrous FS obtained from grey cast iron melted in EIF was selected for this study to replace fine aggregate in a ready-mix concrete plant. The producer usually uses two types of crushed granitic sand in the concrete mix-designs, with the dimensions of 02 mm and 04 mm.
An experimental study was carried out to investigate the strength properties of concrete produced with iron filings as partial replacement for sand. Concrete specimens (cubes, cylinders and prisms) were cast and tested for compressive, split-tensile
Mar 16, 2018· Even so, aggregate that contains pyrrhotite, an unstable form of iron sulfide (Fe[1-x]S), in quantities that are able to be disruptive to concrete does not appear to be very common. In Connecticut, this aggregate came from a specific quarry and was used in concrete supplied from one producer starting in the late 1980s and continuing until 2015.
substitution of natural aggregates of conventional concrete with steel slag (Shailja et al. 2018, Ouda et al. 2017, Huang et al. 2012, Liu et al. 2011). Iron slag also proves to be a feasible sand replacement in self-compacting concrete mixtures in terms of filling ability, passing ability, viscosity,
Durability characteristics of self-compacting concrete (SCC) made with iron slag (IS) are presented in this paper. For this purpose, initially, a control SCC was designed, and then fine aggregates
Iron and steel slag products: Concrete aggregate. In recent years, with restrictions on dredging of marine sand and the stopping of sand imports from overseas, there has been a growing need in society for measures in response to the exhaustion of natural aggregate.
Iron Slag Sand: IS 383 permits upto 25% replacement in RCC and 50% in PCC/ PQC and 100% in Lean Concrete; Copper Slag Sand : Same as above; Fly Ash: Upto 25% replacement in Lean Concrete; Recycled Crushed Concrete.

The slag obtained has properties similar to that of sand and can be used for construction purposes. Ayano T, Sakata K.(2000), [1] proposed a theory on concrete and this theory providesthe feasibility of the usage of iron ore dust as hundred percent substitutes for Conventional Concrete. Figure (a) Iron ore slag used in the present investigation.
Concrete is awesome, but its not the only option for securing, building and paving. There are a good number of concrete alternatives for driveways, fence posts and foundations. This extensive article is broken up into 4 sections and provides substitutes for concrete in two approaches.
Jul 18, 2019· B last Furnace Slag. Just like fly ash, blast furnace slag is a byproduct that can be recycled and used to make an environmentally friendly alternative to concrete. This glassy granular material is produced by quenching molten iron slag from the blast furnace into water or steam.
Firstly, the raw materials of mixing were analyzed, and the test ratio was determined. Secondly, the workability and mechanical property of concrete specimens with different amounts of iron ore tailings as replacement were tested. Results show that 35% replacement of natural aggregate by
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 Furnace (BOF) or in an Electric Arc Furnace (EAF) without making its by-product, steel slag [1]. The use of Iron slag aggregate in
