Characteristics and Uses of Steel Slag in Building ...
Abstract. For a long time, steel slag was not an attractive building material due to some of its adverse properties like volume instability. However, as the steel industry grew, the amount of steel slag as a by-product also increased, and the need for a proper and environmentally acceptable solution for dealing with this material had to be addressed.
Slag Concrete - an overview | ScienceDirect Topics
Alkali-activated slag concrete (AASC) showed greater tensile strain capacity than OPC concrete due to the greater creep, lower elastic modulus and higher tensile strength of AASC (Collins and Sanjayan, 1999b; Chi, 2012).Alkali-activated fly ash concrete (AAFAC) generally shows higher splitting tensile strength than the OPC concrete of similar compressive strength.

30-07-2020 · The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials. Various types of slag are produced: - Blast-furnace slag—The nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other bases, that is developed in a molten condition simultaneously with iron in a blast …
Ground granulated blast-furnace slag - Wikipedia
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing ...
Slag - Wikipedia
Slag 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 ...
Experimental Investigation on Compressive …
31-12-2018 · Concrete of grades M20, M25, M30, M35 and M40 has been considered for studying their compressive behaviour when natural aggregates are being gradually replaced with LD slag. The results obtain showed an increase in compressive strength of the concretes with the increase in percentage replacement of natural fine and coarse aggregates with LD slag.

furnace slag as a partial replacement for Portland cement in concrete if the following limits are met: a. Replace no more than 50 percent of the cement by weight. b. Replace the cement with slag at the rate of 1.0 lb (1.0 kg) of slag to 1.0 lb of cement.
Mechanical Properties of Concrete Using Steel Slag Aggregate
concrete by slag. Concrete of M20, M30 and M40 grades were considered for a W/C ratio of 0.55, 0.45 and 0.40 respectively for the replacements of 0, 30, 50, 70 and 100% of aggregates (Coarse and Fine) by slag. Whole study was done in two phases, i.e. replacement of …
Slag Cement - Lehigh Hanson, Inc.
Slag cement is used in nearly all types of concrete construction: pavements, structures and foundations, mass concrete (i.e., dams and retaining walls) and precast concrete products such as pipe and block. Advocates point to a number of ways in which slag cement makes concrete better and more consistent: • Easier to place and finish
Slag and Exterior Concrete Durability| Concrete ...
01-12-2000 · Slag and Exterior Concrete Durability In our area, people are discussing the benefits or disadvantages of finishing exterior concrete containing ground granulated blast furnace (GGBF) slag. One group claims that since slag is finer than portland cement, a finisher brings more fines to the surface after straight edge and floating and thus creates a less durable surface.

Effects of Ground Granulated Blast Furnace Slag in ...
grade 120 slag cement concrete strength equaled or surpassed that of OPC concrete. Compared to OPC concrete, the time to reach 3000psi traffic opening strength was delayed by 1 to 2 days for 30% replacement and by 3 to 4 days for 50% replacement.
Tarmac | Slag Aggregates
Concrete In concrete, processed steel and blast furnace slag provide a sustainable alternative to primary aggregates in the production of lightweight or dense ready-mixed concrete. Blast furnace slag can also be used to make Ground Granulated Blast-furnace Slag (GGBS) which is used as a cement replacement in concrete.
CPD 24 2015: Introduction to ground granulated ... …
Ground granulated blast-furnace slag (GGBS), manufactured from a by-product of the iron-making industry, is one of the most common, and most sustainable, substitutes. The cementitious properties of blast-furnace slag were discovered in the late 19th century and it has been widely used in concrete manufacture for over 100 years.
