| Summary: | 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 of ultra-fine slag (i.e. 25% of alccofine) as a replacement of cement
for different water to binder ratios (i.e. 0.38, 0.4 and 0.45). The effect of alccofine on the concrete strength
properties were studied at 7 and 28 days wherein considerable strength enhancement was observed compared
to normal concrete. Thermogravimetric analysis was also carried out in which mass loss and decomposition of
hydration products from concrete was determined. X-ray diffraction showed the crystalline forms of ettringite
and calcium silicate hydrate. 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 ecofriendless.
