8 Slag Aggregate. Glass aggregate can replace part or all of the sand and gravel in concrete, for effects that range from colorful terrazzo, to granite- or marble-like finishes, to concrete that reflects light like a mirror.Glass aggregate can even be used to produce concrete that literally glows.8 slag aggregate.

In 8, steel slag was used to replace part of a fine aggregate fraction, in which silica sand amounting to 15, 30, or 50 or fine fraction was completely replaced by slag. In all the mixtures, the coarse aggregate was limestone.
Mar 18, 2011 Two types of slag were used as a substitution of a coarse aggregate 48, 816 mm in mixtures with slags. Particle density on a saturated and surface-dried basis for dolomite used here was 2750 kgm 3, for slag 13210 kgm 3 and for slag 23070 kgm 3. Aggregates used for preparing concrete, were firstly saturated and then surface-dried.
The use of blast furnace slag aggregates in concrete by replacing natural aggregates is a most promising concept because its impact strength is more than the natural aggregate. Steel slag aggregates are already being used as aggregates in asphalt paving road mixes due to their mechanical strength, stiffness, porosity, wear resistance
and magnesia. Steel slag is mildly alkaline, with a solution pH generally in range of 8 to 10. PHYSICAL PROPERTIES Steel slag aggregates are fairly angular, roughly cubical pieces having flat or elongated shapes. Some of the positives of steel slag are. Table 1.Physical properties of steel slag TFHRC accessed 2008 2 MECHANICAL PROPERTIES
Steel slag aggregate SSA is a byproduct of the production of steel in an electric arc furnace. The high iron oxide content of the aggregate results in an aggregate that is very hard and very dense SSA is 20-30 heavier than naturally occurring aggregates such as basalt and granite.
Jun 26, 2020 It was found that steel slag aggregate SSA has superior physical and mechanical properties as well as lower carbon footprint and reduced negative environmental e ects 7,8. The compressive strength of concrete containing steel slag at 28 days was about 35 higher than the reference concrete 9.

slag aggregates in concrete The use of slag aggregates from iron and steel production in construction dates back to the Romans who used crushed slag from the crude iron production to build their roads. Nowadays slag aggregates are seen as value added construction materials

Slag, generally classed as a synthetic aggregate also called artificial aggregate, is produced by altering both physical and chemical properties of a parent material, which may be produced and processed specifically for use as synthetic aggregate.
In agriculture, slag aggregates Ag-Slag have been used as an agricultural liming material since the 1920s in all types of crop production and landscaping. The materials are used to maximise yields of cultivated crops and pasture, improve soil texture and neutralize high soil acidity.
8 9 Steel slag produces an aggregate that Provides excellent resistance to deformation of ruts in surface course asphalt Ensures long life of road surfaces Is hard wearing providing a durable material that will not wear away
Steel slag should be tested for expansion ASTM D 4792 or other approved method prior to use as a base material for pavement.

Slag Aggregates When slag is furnished as an alternate to natural aggregate, the payment is on a weight basis, adjustments must be made to compensate for the difference in specific gravity of the slag compared to the specific gravity of the natural aggregate. For any pay item less than 500 tons on a contract, no adjustment is made.
aggregate, and slag cement replacement levels of 0, 30, and 50 for a total of 24 different types of concrete. In addition, one source of OPC was studied with both aggregates and all replacement levels at a mixing and curing temperature of 40 F. Strength tests were conducted at six ages.

The import quantities for slag mostly granulated blast furnace slag in the USA were 2.3 Mta in 2019 after 2.0 Mta in 2016. In 2016, 8.2 Mta of blast furnace slag was produced, of which only 2.9 Mta 35.4 was granulated slag and 5.3 Mta 64.6 was air-cooled blast furnace slag. In addition, 7.4 Mta of steelworks slag was produced.
