Cement replacement materials are necessary, including coal fly ash, ground granulated blastfurnace slag, silica fume, ground glass natural pozzolans or calcined clay (eg, metakaolin). recycled and waste materials can be used to replace aggregates, materials such as recycled glass, brick and concrete and incineration bottom ash.
Concrete. with addition of copper slag in concrete, the compression strength was increased up to 60 and then a decrement was seen. the strength was increased to 40.75 nmm 2 after the complete replacement of sand with copper slag. the split tensile strength was increased with the addition of copper slag in concrete similar to compressive strength.
Khalifa s al jabri of oman in his findings published in the internationally referred journals such as cement and concrete composites and construction and building materials in 2006 recommends that 50 per cent copper slag can be used as replacement of sand in order to obtain concrete with good strength and durability requirements.

Finely ground slag may be blended with portland cement or added to other ingredients at the mixer. when slag, a byproduct of the ironmaking process, is quenched with water and rapidly chilled, it forms a glassy granulated material of sandlike consistency. because of its high calcium silicate content, it has excellent cementitious properties.
Fineness: granulated blast furnace slag is a glassy granular material, and its particle distribution, shape, and grain size vary, depending on the chemical composition and method of production, from popcornlike friable particles to dense, sandsize grains. pelletized blast furnace slag, in contrast to aircooled and expanded blast furnace slag.
Foamed slag was probably first produced in germany. the lighter types can be used as aggregates in concrete blocks and in insulating concretes, roof screeds, and the heavier ones for structural concrete. in australia, foamed slag was produced by controlled pouring of pot blast furnace slag into specially constructed slag bays.
Glassy, and sandsized particles is generated (i.e., granulated blast furnace slag). when crushed, milled and screened to very fine cementsized particles, ground granulated blast furnace slag has latent hydraulic properties which make a suitable partial replacement for, or additives to, portland cement 3.
Granulated slag is substituted for raw sand, partly or totally. ratios of 25, 50, 75 and 100 by weight of sand are used. the effects of granulated leadzinc slag (glzs) as sand replacement material on the compressive strength and gamma radiation attenuation properties of concrete are investigated and analyzed.
Ground granulated blast furnace slag (ggbs) ggbs, being the byproduct from blast furnace, contains cementitious properties. to develop ultra highperformance concrete, higher cement content ( 600kgm3) is required, which in turn, results in higher heat of hydration.
