Use of Ultrafine Slag in High Strength Concrete

Shamshad Ahmad | Mohammad Shakeel | Sirajuddin Ahmed

Abstract: This paper presents the effect of Ultrafine Slag in high strength concrete with cement replacement of 5 %, 10 %, 15 % and 20 %. Nowadays high strength concrete generally made with Ordinary Portland Cement. In this investigation Portland Pozzolana Cement (PPC) Fly ash based was used to make concrete more environmental friendly. In this experiment five mixes were prepared in which one mix was controlled with plain PPC and four mixes were prepared with 5, 10, 15 and 20 % cement replacement by ultrafine slag (Alccofine 1203). Thus result shows that due to unique particle size distribution of Ultrafine slag forms dense pore structure which results in improved flowability at reduced admixture dosage, improved early strength and compressive strength at all ages in comparison to control PPC mix.
