Sachithanantham et al. studied the replacement of cement by slag powder at different percentages (5, 10 and 15%). In this case, the workability of the fresh concrete increases by adding foundry slag and the compressive strength of concrete increases by adding slag to a maximum of 10% Sachithanantham et al., 2012). Devi et al. studied the ... manufactured with the same 8% Cement, 60% Fly ash and 32% fine aggregate. The Dry compressive strength for 40% replacement of sand with waste foundry sand and 50% replacement of sand with Granulated Blast Furnace Slag at 28 days of curing is 10.3% and 10.1% more than that of Fly ash bricks with no replacement of sand.
The use of GGBFS as a partial Portland cement replacement takes advantage of the energy invested in the slag making process and its corresponding benefits with respect to the enhanced cementitious properties of the slag. Grinding slag for cement replacement requires only about 25 percent of the energy needed to manufacture Portland cement. 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.
This paper demonstrates the use of waste foundry sand as a partial replacement by fine aggregate and slag is as coarse aggregate in concrete. An experimental investigation is carried out on concrete containing waste foundry sand in the range of 0%, 20 %, 40% by weight and slag is fully replaced () for M-25 grade concrete (OPC). 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 industrial by-product of an iron blast furnace.

The possibility of utilization of locally produced Induction Furnace (IF) steel slag as coarse aggregate in concrete blocks was explored. Steel slag was collected from a local steel plant. X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD) analysis replacement of sand) while corresponding strength for normal concrete was just 30.23MPa. Though she warns that with higher levels of replacements (100 per cent) there might be some bleeding issues and, therefore, she recommended that up to 80 per cent copper slag and ferrous slag can be used as replacement of sand (Meenakshi Sudarvizhi 2011).
cement replacement in concrete, or as raw material has the dual benefit of eliminating the cost of disposal and lowering the cost of the concrete. The use of copper slag in the concrete industry as a replacement for cement can have the benefit of reducing the … So, the present study focuses to replace sand by welding slag (WS) and furnace slag (FS) in the production of concrete. Properties of aggregates and slag were studied in detail. M25 concrete was designed for various percentages of slag, and compressive strength of concrete was found out.
