Steel slag - Slag industry news from Global Slag

Carbicrete is developing a technology that allows the production of concrete without using cement by using steel slag instead. The concrete mix is poured into molds, like conventional concrete, and is then cured using CO 2. During curing, the gas becomes a solid, binding together the slag granules, and giving the concrete its strength.

Abstract The present study emphasizes the potential use of Argon Oxygen Decarburization (AOD) steel slag in concrete production. Five mixes along with the control mix were made by partially replacing cement with AOD steel slag varying from 10%, 15%, 20%, and 25%. The different properties of all the concrete mixes were evaluated by assessing slump, compressive strength, flexural strength and ...

RECYCLED CONCRETE - Portland Cement Association

140 million tons of concrete are recycled each year in the U.S. alone. Typically, recycled concrete aggregate (RCA) is used as granular fi ll, base and sub-base material, or as aggregate in new concrete pavement. Why do it? Reusing concrete pavement minimizes the amount of raw materials required for a new pavement structure.

Recycling of steel slag aggregate in portland cement ...

Abstract. Because of the unique physical and chemical characteristics of steel slag, steel slag aggregate (SSA) has been recycled into Portland cement concrete as a substitution for natural aggregates as a sustainable and low impact design solution by reducing the use of natural resources and the landfills for disposal.

Aggregate Properties You Need to Know: Strength ...

Construction aggregates are mineral materials used in the production of construction materials such as Portland cement concrete and hot-mix asphalt, and as unbound base courses for pavements. In their primary role as filler in these materials, the volume of aggregates can take up 90 – 95% of asphalt and 70 – 80% of concrete mixtures.

CRSI: Recycled Materials

The steel is sold to plants and reused as new quality steel products. More than 65% of all reinforcing bars are recycled, according to The Steel Recycling Institute. Likewise, the concrete can be crushed and reused as aggregates in new concrete structures, in roadbeds, and for breakwaters as larger pieces.

Embedding metal letters into concrete. A how-to article

Embedding stud mounted letters into the concrete does definitely help to maintain stability. Without the studs penetrating the concrete, the letters would soon come loose and disappear. A better way, although far more costly, would be to embed the letters using a stabilizer plate (above). For outdoor applications, stainless steel would be the ...

Concrete Structures - MIT OpenCourseWare

Concrete is an ideal medium for recycling waste or industrial byproducts. Many materials that would end up in landfills can be used instead to make concrete. ! Concrete is modest in its energy needs and generous in its payback. The only energy intensive demand is in the manufacture of portland cement, typically a 10-15% component of concrete. !
