The replacement of Portland cement has been studied by various authors. Partial replacement of hydraulic cement with cupola slag was patented by Stroup, Stroup and Fallin (Stroup et al. 2003). The authors claimed in their patent that a way to blend cement with cupola slag was invented.
Furthermore, adding finely-ground granulated slag from cupola to the cement slink, ... that reasonably high strength concrete can be designed by substituting fine aggregates with 10% to 45% of foundry slag and a partial replacement of cement with 15% of Alccofine.
concrete when it partial replaced with palm oil fuel ash as cement, cupola slag powder as fine aggregate, brickbat for coarse aggregate. Initially, in this study cement is being replaced with palm oil fuel ash in different percentages (5%, 10%, 15%, 20%) to get an optimum strength particular replacement percentage.
replaced coarse aggregates fully with cupola slag in all mix and partial replaced of cement by slag cement. 0%, 2%, 4%, 6%, 8%, and 10% replacement of cement was taken. They conclude that higher strength is obtained for 2% cement replacement, while …
Mortars have also been manufactured with normalized sand and with Portland cement replacements (0, 10, 20, and 30% by weight) with cupola slag, and both the consistency and the mechanical ...
Partial Replacement of Portland Cement by Granulated Cupola Slag – Sustainable Option for Concrete of Low Permeability This paper presents the results of investigation on the potentials of cupola slag as a partial replacement option for ordinary Portland cement (OPC) in applications requiring low permeable concrete.
cupola slag as partial replacement of sand inconcrete. In this present study cupola Slag is used to replace fine aggregates from 0% to 50% and fly ashis used to replace OPC from 0% to 35%. Concrete cubes, cylinders and beams were cast and their compressive strengths, tensile strength and
Very few studies are documented in literature regarding the feasibility of utilizing cupola slag as partial or full replacement of aggregates or cement in concrete. Baricova et al. [ 10 ] explored the possibility of using blast furnace slag in combination with cupola slag as complete replacement of coarse aggregates in concrete production.

The effect of partial replacement of cement by cupola slag on the compressive strength of cement mortar was investigated by varying the slag content (from 0 to 40%) of a standard cement; graded sand (1 : 2.75) mix and testing at 7 and 14 days while the water: (cement + slag) ratio was kept at 0.5 throughout.
granulated blast furnace slag is better replacement of cement than various other alternatives. The rateof strength gain in slag replaced concrete is slow in early stages but with proper curing the strength goes on increasing tremendously. The compressive strength decreases when the cement replacement is more than 50%. Use of slag or
Cupola slag is by product of cast iron manufacturing unit. Cast iron slag is substitute with fine aggregate and cupola slag is substitute with coarse aggregate with optimum percentage of replacement to check the appropriateness of concrete strength, durability, workability and ecological achievability.
