uses of steel slag and fly ash

(PDF) Characterisation of LD slag of Bokaro Steel Plant ...The compressive strength of the brick samples type A (Fly ash - 35% + LD slag - 30% + Gypsum - 5% + Quarry dust - 20% + Lime - 9.75% + CaCl2 - 0.25%) was found to be more than 100 kg/cm2 after 14 ...WHY USE FLY ASH AND SLAG IN CONCRETE? - Bay-Lynx ...Slag is produced by the steel production industry. Slag happens when iron ore is melted. The molten iron sinks to the bottom, while the slag will float on the top of the iron. See the diagram below: Another difference between slag and fly ash is that while fly ash will rarely surpass 35% of the cement content, slag can substitute 50% of the ...Fly Ash for Concrete: Properties, Uses, Advantages ...Since many years, fly ash is being used in the concrete. According to 'M.S. Shetty' (Author of Concrete Technology Theory and Practice), that the first large scale use of fly ash was in the construction of Hungry Horse dam and later, Canyon Ferry dam in United States of America. The amount of fly ash used was about 30% by weight of cement.Fly Ash/Blast Furnace Slag-Based Geopolymer as a Potential ...This article investigated the potential of fly ash (FA)/blast furnace slag- (BFS-) based geopolymer as a novel backfilling material. The effects of NaOH concentration and FA/BFS mass ratio were explored through XRD, FTIR, and TG-DTG analyses. The results indicated that the reaction products and strengths of geopolymer depended on the NaOH concentration and types of source materials.

Use of Soil-Steel Slag-Class-C Fly Ash Mixtures in ...

Use of steel slag, fly ash and blast furnace slag in road applications, such as in subgrade stabilization projects, can be a cost-effective alternative to lime stabilization in some cases. In addition, use of large quantities of these underutilized industrial by-products in these types of applications helps to reduce the need for new disposal ...Fly ash - WikipediaFly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.Slag - WikipediaSlag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...project on steel slag ggbs and fly ashFly Ash, Slag, Silica Fume, and Natural Pozzolans Fly ash, ground granulated blast-furnace slag, silica fume, and natural pozzolans, such as calcined shale, calcined clay or metakaolin, are materials that, when used in conjunc-tion with portland or blended cement, contribute to the properties of the hardened concrete through hydraulic orThe Difference in Slag Cement and Fly Ash - Slag Cement NewsOnce a good relationship with a supplier is established, slag cement can be used at a higher percentage than fly ash. In most cases, slag cement can be used as a 30-50% replacement to portland cement, reducing the carbon impact of the concrete. To check for suppliers in your area, use the SCA's slag .
