Due to its positive technical characteristics, LD slag is used all over the world in road and railway construction and for engineering. The most common use is as an aggregate in the manufacture of asphalt. It is also successfully used as an aggregate for concrete. Slag

SLAG is a broad term covering all non metallic co products resulting from the separation of a metal from its ore, Its chemistry and morphology depends on the metal being produced and the solidification process used. Slags can be broadly categorized as ferrous (iron/steel) and nonferrous (copper, lead/zinc) depending on the
Bottom ash and boiler slag have been used in stabilized base applications. Stabilized base or subbase mixtures contain a blend of an aggregate and cementitious materials that bind the aggregates, providing the mixture with greater bearing strength. Types of cementitious materials typically used include Portland cement, cement kiln dust, or

Copper slag used in this work was brought from Oman Mining Company, which produces an annual average of 60,000 tons. 3.4 Silica fume The silica fume used in the production of high strength concrete was supplied and added to the mix in a powder form (Elkem Emsac 500s). 3.5 Superplasticizer

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
INTRODUCTION. Ground granulated blast furnace slag (GGBFS) has been used for many years as a supplementary cementitious material in Portland cement concrete, either as a mineral admixture or as a component of blended cement. The use of GGBFS in Portland cement is governed by AASHTO M302.
2020521&ensp·&enspThe history of slag use in road building dates back to the time of the Roman Empire, some 2000 years ago, when broken slag from the crude ironmaking forges of that era were used in base construction. Roads made from Slag were first built in England in 1813 and, just seventeen years later, the first Slag road was laid in this country.
