Benefits of using slag cement. Q. What are the benefits of using slag cement? A. The hydration products of slag cement are generally found to be more gel-like (less crystalline) than the products of hydration of portland cement; thus, they reduce the permeability of the cement paste (ACI 233R).
Desc: Information on the use and benefits of slag cement (ground granulated blast furnace slag) in concrete and other construction applications.

Benefits Of Slag Cement. Factors Affecting the Durability of Concrete and the . Volume 6, Issue 1 (July 1984) Factors Affecting the Durability of Concrete and the Benefits of Using Blast-Furnace Slag Cement.
Slag is a product of the steel making process. Once scorned as a useless byproduct, it is now accepted and, often, preferred and specified as it is known to be a valuable material with many and varied uses.
Environmental and LEEDS Benefits. In addition to it's high strength and durability, slag cement is an environmentally "green" product. In providing a beneficial use of an industrial by-product, it reduces the energy required to produce concrete while at the same time improving the quality of the concrete for a more durable, longer lasting ...

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 industri
The use of ground granulated blast furnace slag and powder coal fly ash as an addition to either cement or concrete is well-established. Concrete made with these secondary raw materials as a part of the binder does show distinctive advantages over concrete with Portland cement only.
In the case of cement manufacture, the use of granulated blast furnace slag instead of clinker reduces the overall process CO 2-emissions as a result of fuel savings and avoidance of sintering limestone or other calcareous materials.

The ground granulated blast furnace slag (GGBFS) is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degree
synergistic and environmental benefits of using cement kiln dust with slag and fly ash in cemented paste tailings (thesis format: integrated-article)
Thus, for equal weight of cement and equal water contents, this increase in paste volume generally benefits workability in mixes with low cement contents or where the aggregates lack the fine fraction. Setting Time . The setting times for blended cements are generally longer than for Portland cements. As the percentage of slag increases in the blended cement or the concrete the setting or ...
It is also successfully used as an aggregate for concrete. Slag use is subject to strict regulations and standards. The use of slag is clearly regulated for particular applications.
Slag cement is a recovered byproduct of the iron manufacturing process and can be used to replace a portion of portland cement in concrete mix design. The use of slag cement has demonstrated long-term performance enhancements allowing designers to reduce the environmental footprint of concrete while ensuring improved performance and increased durability.
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 as a partial Portland cement …

Agricultural Benefits In areas where iron and steel are manufactured, an agricultural blast-furnace slag product, including ladle metallurgical furnace slag, may be available as an economical alternative to agricultural limestone or dolomite and as a better source of micro nutrients.
The concrete made with Ground Granulated Blast Furnace Slag cement sets more slowly compared to ordinary Portland cement concrete based on the amount of GGBS in the cementations material. It also needs longer period to gain required strength.
Slag cement is hydraulic and can be added to cement as an SCM. Silica fume, also called condensed silica fume or microsilica, is a finely divided residue resulting from the production of elemental silicon or ferro-silicon alloys that is carried from the furnace by the exhaust gases.

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.
Slag cement, a byproduct of steel-making, enhances the traditional concrete benefits of strength and durability while offering reductions in waste, energy use and greenhouse gas emissions.
As a common practice, blast furnace slag is incorporated in Portland cement production for environmental, technical and economical benefits. Before JSW Cement's entry in the market, 'green cement' was virtually unheard in southern and western India.
PSC - Portland Slag cement is a kind of blended cement manufactured either by grinding the Portland clinker with gypsum and granulated slag or by blending the ground granulated blast furnace slag (GGBS) with Ordinary Portland cement.
What are the disadvantages of Portland slag cement? If you were where I am, I'd suggest the first and most apparent disadvantage is that it indicates that you are not familiar with the terminology we use. I think you are talking of a blend of Portland cement and GGBFS (usually called "slag
