An Experimental Study on the Compressive Strength of Alccofine with Silica Fume Based Concrete

This investigation is focused on the physical and mechanical properties of Alccofine (AF) incorporating silica fume (SF) on M20 grade concrete. Normally, these industrial wastes (SF) are disposed off in landfill. The use of these industrial waste in concrete could reduce waste in the environment as well helps the environment against pollution as it is known that one ton of cement manufacture released one ton of carbon dioxide to the environment .Alccofine is a new replacement material on which very limited research has been done, its effect with flyash has been studied. The current study is a new experimental research undertaken to study the effect of alccofine on SF based concrete. Alccofine was varied in percentages of 0, 5, 10 and 15%, Silica fume was varied in percentages of 0, 5, 10, 15 % The aim of the investigation was to see the effect of alccofine on compressive strength of concrete and do a comparison on 7, and 28 days strength.The results showed that the cement replacement by 10% of alccofine gives higher values when compared with all other mix. The cement replacement by 10% alccofine gave a good improvement in compressive strength. Alccofine has the better performance when compare to the other slag material. It is helpful to make concrete workable
