چکیده انگلیسی


• Effect of commercially available ultrafine slag as partial replacement to cement in high strength concrete was studied.
• Properties of hardened concrete namely compressive strength and durability characteristics was studied for commercially available ultra fine slag.
• It was inferred that concrete with commercially available ultra fine slag performs inferior to concrete with ground ultra fine slag.
• Concrete with 10% ultra fine slag was found to be optimum in terms of strength and durability characteristics. Cost analysis also justifies the same.

Ground granulated blast furnace slag (GGBFS) in the present research work was commercially available ultra fine slag of size 5 μm meter was used which fills micro voids. This paper deals with compressive strength, porosity and sorptivity characteristics of commercially available ultra fine slag based high strength concrete (HSC) (with a characteristic compressive strength of 50 MPa). The results were compared with similar characteristics of precursor slag and ultra fine slag obtained by grinding (Sharmila and Dhinakaran, 2015). Ultra fine slag replaces cement with three different percentages viz 5, 10, and 15% to study the compressive strength, porosity and sorptivity. Performance of commercially available ultra fine slag was found to be inferior than ground one and concrete with 10% ultra fine slag was found to be optimum.
