EFFECT OF STEEL SLAG AND FLAY ASH ON THE PROPERTIES OF CONCRETE MIX FOR PAVEMET; Author(s): RAHAT GUL ZIARMAL, Prof. Rena N. Shukla: Keywords: Abstract: the global demand of concrete in the future is more challenging task to find the suitable alternatives of natural aggregates, sand and cement for preparing concrete.
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 cement content, or even higher for different applications. This contributes to the large cost savings from slag cement. Fly ash is more of a smooth particle rather than slag's rough and jiggered texture.

The Slag Cement Association with member company and industry input have broken down the differences in slag cement and fly ash and how they both affect concrete performance. 1: Slag cement has a more consistent chemical and physical structure than fly ash from source to source and from a single source. What does that mean for your concrete?
01-10-2019· Fly ash and slag addition improves transport properties of concrete after exposure to high temperatures. Better bonding of chloride ions by slag than fly ash : 2: OPC blend with 50%/70%/90% FA or GGBFS and mixture of GGBFS and FA (FA:GGBFS = 1:1, 1:2, 2:1) FA
Technical Issues Related to the Use of Fly Ash and Slag During the Late-Fall (Low Temperature) Construction Season Introduction Current INDOT specifications (Section 501.03) permit the use of fly ash and slag in concrete pavement only between April 1 and October 15 of the same calendar year. This
Home / Blog / Differences between fly ash, slag and silica fume Supplementary Cementitious Materials (SCM) are added to concrete mixtures for various reasons including improving durability, decreasing permeability, aiding in pumpability and finishability, mitigating alkali reactivity and improving the overall hardened properties of concrete through hydraulic or pozzolanic activity or both.

21-10-2013· Fly ash and ground granulated blastfurnace slag (GGBS) are regarded as conventional cement constituents in much of the world. The proportions used in concrete-making vary quite considerably and the price of the material is key when it comes to producing a cubic metre of concrete to the required specification at the lowest possible cost.
29-01-2015· RE: Fly Ash vs Slag in Liquid Containing Structures Gumpmaster (Structural) 29 Jan 15 20:32 Well, if you haven't heard, there is somewhat of a national fly-ash shortage (which does vary greatly by region) due to natural gas prices and other variables.
