What is slag cement

Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace.

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.

Welcome to Skyway Cement Company

Blast-furnace slag is produced in a blast furnace during the reduction of iron ore to iron. It consists of non-metallic minerals, which are tapped off from the blast furnace while molten. By processing blast furnace slag into Skyway Cement or slag aggregate, the material is diverted from landfills.

Common Uses for Slag | National Slag Association

Blast furnace slag products have been used successfully in virtually all phases of bridge construction. Projects such as the bridge pictured here can utilize blast furnace slag as a concrete aggregate. Blast furnace slag has been utilized in concrete masonry for many years.

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.
