Concrete Made From Slag Aggregate

Durability of concrete made with EAF slag as aggregate ...

Electric arc furnace (EAF) slag, a by-product of steelmaking recovered after the oxidizing process, is useful when employed as aggregate in hydraulic concrete and bituminous mixtures. Concrete made with EAF oxidizing slag as an aggregate shows good physical and mechanical properties and further study of its durability will ensure greater reliability in its usage.

Tarmac | Slag Aggregates - Aggregates | Asphalt | Cement

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.

Construction aggregate - Wikipedia

Construction aggregate. Sources for these basic materials can be grouped into three main areas: Mining of mineral aggregate deposits, including sand, gravel, and stone; use of waste slag from the manufacture of iron and steel; and recycling of concrete, which is itself chiefly manufactured from mineral aggregates.

Durability of concrete made with EAF slag as aggregate ...

Concrete made with EAF oxidizing slag as an aggregate shows good physical and mechanical properties and further study of its durability will ensure greater reliability in its usage.

Properties of pervious concrete made from steel slag and ...

The new pervious concrete (PC) were prepared using magnesium phosphate cement (MPC) as binding and waste steel slag as coarse aggregate. A series of laboratory experiments were carried out to study the influence of aggregate size and molding method on the compressive strength, flexural strength, porosity and water permeability coefficient of magnesium phosphate cement steel slag pervious …

Environment-Friendly Block, “Ferroform,” Made from Steel Slag

consisting mainly of steelmaking slag (corresponds to aggregate), ground granulated blast furnace slag (cor-responds to binder) was developed. Ferroform has the same strength and durability as concrete. It can be used a substitute for concrete blocks, natural stones and fresh concrete. In repair work at Mizushima Port, 150 000 t of

Common Uses for Slag | National Slag Association

Crushed and graded - for concrete aggregates, concrete sand, glass insulation wool, filter medium, and use under concrete slabs as a platform 2. By passing the molten slag through high volume high pressure water sprays, a glassy, sand-Type (granulated) material Is formed, known as Granulated Blast Furnace SIag.The color of this product is very similar to normal beach sand.

Utilization of Steel Slag in Concrete as Coarse Aggregate

Concrete made with heavyweight slag aggregate gives more compressive strength than other aggregates. Relationships between compressive strength …

How Cement Is Made

Cement is manufactured through a closely controlled stone combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

A Study on Suitability of EAF Oxidizing Slag in Concrete ...

The study was conducted to define and analyse the physical, mechanical, and durability properties of eco-friendly concrete made with 50% EAF oxidizing slag aggregate in addition to 30% fly ash (Mix C) compared with conventional concrete mix (Mix A) and concrete …

Frost Resistance and Air Void System of Self-Compacting ...

Test results are summarized as follows: (1) The air-void system of self-compacting concrete with slag fine aggregates varied depending on the type of slag fine aggregates used in this investigation. Especially, self-compacting concrete with BFS fine aggregates showed much larger air-voids.

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.

concrete made from slag aggregate

The two types of concrete aggregate that are manufactured using iron and steel slag as a raw material and which are covered by JIS standards are blast furnace slag aggregate and electric arc furnace oxidizing slag aggregate Each of these types includes course aggregate and fine aggregate
