Abstract: The supplementary cementitious materials (SCM) can be used as a replacement of cement in the construction industry to minimize the drawbacks of normal concrete such as the emission of carbon dioxide so as to be eco-friendly. This paper presents the effect on the properties of concrete with ultrafine slag dosage (i.e. Alccofine of 25%) as a replacement of cement for different water to binder ratios (i.e. 0.38, 0.4 and 0.45). The effect of addition of alccofine on the strength properties (compressive strength, splitting tensile strength and flexural strength) of concrete were studied at 7 and 28 days wherein considerable strength enhancement was observed compared to normal concrete. Water absorption and the effects of acid attack on weight and strength deterioration factor (SDF) were also carried out. It was identified that the concrete with alccofine was more durable as compared to normal concrete. Therefore, it was concluded from this study that alccofine can be used as a viable substitute to cement in normal concrete considering its positive effects on property enhancement and eco-friendless.
