Steel slags are industrial by-products of steel manufacturing, characterized as highly calcareous, siliceous and ferrous. In such preparations OPC clinker is about 15-30%, steel-slag around 30-40% and blastfurnace slag is around 40-50%. Portland cement, class strength 52.5 R, was used because this cement contains 95–100% Portland cement clinker. Cement-based materials will remain essential to supply the growth of our built environment. Parron-Rubio, M.E. It is speculated that the higher early strength of LFS mixtures may be related with higher CaO content of LFS, when compared to GGBS. environment. Studies have indicated that adequate aging/weathering and treatments can enhance the hydrolyses of free-CaO and -MgO to mitigate the instability. In Proceedings of the International Workshop organized by JCI (Japan Concrete Institute), Hiroshima, Japan, 3–8 June 1998; pp. For steel slag used as a coarse aggregate in a bound condition, or in a rigid matrix, such as PCC, the resulting integrity and volume stability are basically controlled by the minimum allowable stress of the matrix materials, cement mortar for instance, and the maximum expansion stress, which can be deduced from the expansion force based on appropriate modeling of steel slag particles in the matrix. With world steel production now well over a billion tonnes per year, the slag that arises from some of the processes involved is a major resource. Ground granulated blast-furnace slag (GGBFS) Our slag cement CEMSlag TM is a hydraulic cement material created when granulated blast-furnace slag from the steel manufacturing process is ground to a fineness suited for concrete production.

Since this research is part of a larger project that is studying the use of landfill slag as a concrete constituent, for the production of precast concrete, the concrete dosage has been designed in order to meet a dry consistency. The swelling underwater of GGBS and LFS mixtures was similar. The two major applications of steel slag in concrete are used as a mineral admixture for cement and as an alternative to natural aggregates. Considering the environmental and economic aspects, steel slags are also considered to have a potential use as the raw meal in cement clinker production. NP EN 196-1:2006—Métodos de ensaio de cimentos. However, better utilization for value-added purposes in cement and concrete products can be achieved. Since 1960 is used to the cement production the blast furnace slag, by-product of the pig iron production in the blast furnace, which presents the relationship CaO/SiO 2 between 0.9 and 1.2 [2]. The iron is used to produce steel, and the molten slag is converted to a cement-like material by rapidly cooling it with water. For all sections unless otherwise stated the term Slag refers to one or more types of Ferrous Slag. ; Gartner, E.M. Parron-Rubio, M.E. Two samples of raw meals were prepared, one with ordinary raw materials, as a reference sample ((PC)(Ref)), and another with 10.5% steel slag ((PC)(S/S)). [, Rubio, M.E.P.
