Crushing Plants

Mobile crushing plants are built ready-mounted on their own travel gear. Semi-mobile plants, on the other hand, are moved from one location to the next as a piggyback load on separate haul units. Each crushing plant comes ready to operate with its own feed hopper, feed conveyor, discharge conveyor and material transfer belt. The size and design of the crusher naturally depends upon the work that it is intended for.

Crushing Plants

Semi-mobile crushing plants are always to be recommended when a change of location in long periods is required in order to optimize the raw material transportation- and operational-costs of the quarry department.

Effects of Ground Granulated Blast Furnace Slag in Portland

Slag cement is often referred to as “ground granulated blast-furnace slag” (GGBFS). As requested in 2001 by slag cement manufacturers and the Slag Cement Association, the American Concrete Institute officially reviewed and changed the terminology from GGBFS to slag cement (ACI Committee 233, 2004).

Table 1 - Chemical composition of EAF slag.. The basicity index of the slag calculated based on CaO/SiO 2 and CaO/(SiO 2 +P 2 O 5) works out to be 1.85 and 1.78 respectively.The relationship between basicity, phase composition and hydraulic activity of steel slag as reported in the literature is given in Table 2.

Iron and Steel Slag Statistics and Information

Iron and Steel Slag Statistics and Information Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent.

The alternative material now being used is a blend of con-struction industry grade ground granulated blast fur-nace slag (GGBS) and a coarser fraction glassy slag of a similar chemical composition called Calumite [3]. By blending the finer GGBS with the coarser Calumite

How Cement Is Made

Cement is manufactured through a closely controlled chemical 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.

“Ground Granulated Blast Slag (GGBS) In Concrete – A Review”

II. Chemical Composition Of GGBS The chemical composition of a slag varies considerably depending on the composition of the raw materials in the iron production process. Silicate and aluminate impurities from the ore and coke are combined in the blast furnace with a flux which lowers the viscosity of the slag.

CHAPTER 1 COMPONENTS OF CONCRETE

CHAPTER 1 COMPONENTS OF CONCRETE Concrete is made up of two components, aggregates and paste. Aggregates are generally classi! ed into two groups, ! ne and coarse, and occupy about 60 to 80 percent of the volume of concrete. The paste is composed of cement, water, and entrained air and ordinarily constitutes 20 to 40 percent of the total volume.

Chemical Composition of Cement

Chemical Composition of Cement The raw materials used for the manufacture of cement consist mainly of lime, silica, alumina and iron oxide. These oxides interact with one another in the kiln at high temperature to form more complex compounds. The relative proportions of these oxide compositions are responsible

Ground granulated blast-furnace slag

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.

Standard Specification for Slag Cement for Use in Concrete

1.1 This specification covers slag cement for use as a cementitious material in concrete and mortar. Note 1: The material described in this specification may be used for blending with portland cement to produce a cement meeting the requirements of Specification C595/C595M or as a separate ingredient in concrete or mortar mixtures.
