Why use Fly Ash and Slag in Concrete? - Bay-Lynx ...
With cement being the costliest ingredient, substituting fly ash or slag can help maintain a stronger mix at a lower cost. Fly ash and Slag will typically be 18% cheaper than Portland cement. When a mix includes 20% fly ash, this will provide savings of 3.5% in cost. The advantage of slag is its ability to substitute more of cement. Giving savings of up to 9% in cement cost with a 50% slag to cement …
Utilization of steel slag, iron tailings and fly ash as ...
15.12.2014 · Iron tailings, steel slag and fly ash were used to replace river sand for preparing the mortar. For determining a reasonable ratio of them, effects of the aggregate ratio on mechanical properties of mortars were investigated. As shown in Table 3, iron
USE OF GRANULATED BLAST FURNACE SLAG, STEEL SLAG AND …
furnace slag (GGBS), fly ash and steel slag can be used at certain percentages and curing periods as additive in cement-bentonite barrier wall construction. Permeability of specimens having fly ash decreases by increasing fly ash content. Mixtures having 50 % of GGBS type I with 5 % of lime and
Use of Steel Slag in Subgrade Applications
EAF(L) slag and mixtures of steel slag and Class-C fly ash can be used in the design of various types of geotechnical projects, such as small roads and highway embankments. Based on the experimental results, we suggest the use of mixtures of BOF slag and 10% Class-C fly ash and of EAF(L) slag and 5-10% Class-C fly ash in
Slag cement with fly ash - Slag Cement Association
Slag cement and Class F fly ash will both provide protection against sulfate attack and ASR. Class C fly ash may not provide this protection. Color. Slag cement will provide lighter concrete with higher reflectivity than plain portland cement concrete. Class C and Class F fly ash will produce, respectively, a buff or darker gray concrete.
The Difference in Slag Cement and Fly Ash - Slag …
Fly ash and slag cement work well together in certain applications and can be used to achieve higher strength gains, corrosion resistance and lowered concrete permeability. The optimum mixture proportions for ternary blends, as with other concrete, will be dependent on the final use of the concrete, construction requirements and seasonal considerations. In low W/CM applications such as paving, …
Resilient Response and Permanent Strain of Steel …
In this study, engineering properties of steel slag-fly ash-dolime (SFD) mixes were investigated for their effective utilization as base course material in flexible pavements. The effects of fly ash and dolime percentages and the curing age on the resilient modulus and permanent strain of SFD mixes were investigated. The performance of various stress-dependent models for the prediction of resilient …
Coal fly ash and steel slag valorisation throughout …
18.09.2017 · The aim of this research was to evaluate the feasibility of using the vitrification process as an alternative solution to the disposal of a coal fly ash and metallurgical slags in landfills. The starting wastes were characterised in terms of chemical, granulometric, mineralogical, and microstructural analysis. A selected batch composition composed by 58.5% fly ash, 31.5% metallurgical slag and ...

Performance of Steel Slag and Fly Ash Added Soil …
29.03.2018 · The results showed that when steel slag and fly ash are used with clay, there were significant increases in their bearing ratios compared to the reference clay sample. While the wet California Bearing Ratio (CBR) was around 15% for the normal clay sample, when it is blended only with steel slag the wet CBR increased up to 70%, and when blended with fly ash the wet CBR went up to 130%. The used ...
WHY USE FLY ASH AND SLAG IN CONCRETE? - …
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 ...
3D printing concrete made from fly ash and steel …
05.02.2018 · Fly ash consists of fine particles of fuel that are driven out of coal-fired boilers, while steel slag is by-product of the steel industry, left over after a metal is separated from its raw ore. Both materials have been used as additive to cement before, but are now used together with only the addition of some chemicals to make a concrete like material that can be 3D printed.
