Ordinary Portland Cement is made by grinding Clinker with a few other minerals. Other Cements such as limestone Cements, Pozzolanic Cements, Blast Furnace Slag (BFS) Cements, and masonry Cements, contain greater amounts of other minerals and have a much broader composition range. Clinker is made in a chemical process which is energyintensive.

steel slag admix cements in tehran. slag of France, the hydraulic properties of this slag is weak and lacks any pozzolanicity (Mieux et al., 2009). In Iran the converter slag of Esfan Steel Company is used in the base and sub base road superstructure. The results showed that this slags have good durability and reliability, high toughness
The steel slag for this study was obtained from a steel mill in Suzhou, China. The limestone was sourced from a stone plant in Wuxi, as shown in Fig. 1, and the standard MPa cement was used as a physical and mechanical characteristics of two aggregates were tested, with the results shown in Table apparent densities of steel slag and limestone employed are quite
Slag cement, or ground granulated blast furnace slag (GGBFS), has been incorporated into concrete projects in the for over a century to improve durability and reduce life cycle costs. Among its measurable benefits in concrete are better workability and finishability, higher compressive and flexural strengths, and improved resistance to aggressive chemicals.
For this purpose, a reference sample and three cements containing up to 45% w/w steel slag were tested. The steel slag fraction used was the quot;05 mmquot;, due to its high content in calcium silicate
Passivation of reinforcing steel exposed to synthetic pore solution and the effect of calciumnitrite inhibitor (Tullmin, M, Mammoliti, L, Sohdi, R, Hansson, CM, and Hope, BB), Dec., 134 Cement analysis New consecutive dissolution method for the analysis of slag cements (Goguel, R), June, 84 Ceramic tile
Keywords Steel slag, bitumen, ductility test 1. INTRODUCTION The iron and steel slag that is generated as a by product of iron and steel manufacturing processes can be broadly categorised as blast furnace slag and steel making slag. Blast furnace slag is recovered by melting,separation from blast furnace that produce molten pig iron.

tions of blended cements. Granulated blast furnace slag is similar to the chemical composition of Portland cement. The slag has a latent hydraulic property; it begins to hydrate and harden when it is stimulated by alkali from cement. Therefore, compared with other kinds of blended cements, PBFSC allows for a larger proportion of admix
entday blended Portland cements are made with admixtures (as per EN) of blastoven slag, fly ashes, puzzolans, respectively SiO 2 fly ash. Very fine waste steel and foundry dust on the basis of iron oxides has not been used as admixture to blended Portland cements yet and there are no
Steelslag and its characteristics. It is estimated that 115180Mt of steelslag is poured out annually worldwide and in addition to this previous accumulation of the material has created mountains of steelslag. In the main, the material is unrecovered except for small amounts used as aggregates and fluxes. Types of steelslag
Cement is a fine powder, obtained from the calcination at 1,450#176;C of a mix of limestone, clay, and iron ore. The product of the calcination process is clinkerthe main ingredient of cementthat is finely ground with gypsum and other chemical additives to produce cement.

#0183;#32;In fact, the production of slag cements and slagblended Portland cements results in resource conservation, reducing energy consumption and minimizing emission of GHGs, especially CO2 . Blast furnace slag (BFS) as one of the industrial solid wastes is formed in a molten state simultaneously with iron in a blast furnace.
The Iranian cement sector traces its origins back to 1933, when the first plant, of just 100t/day, was built to the south of Tehran by Denmarks FL. Subsequent capacity was added in 1937, taking the total capacity to 9000t/yr, before more significant expansion in the 1950s and 1960s (See Figure 1). 1
