Experimental study of strength relationship of concrete cube and concrete cylinder using ultrafine slag Alccofine

Abstract

This paper presents a comparison between cubical strength and cylindrical strength of normal concrete and with partial replacement of cement with ultra fine slag (Alccofine). Ultra fine slag materials are very much important for improving the durability and workability of concrete to sustain a longer life span and producing a greener and quality concrete. Incorporating ultra fine slag as a mineral admixture improves the workability and pump ability of fresh concrete. The ultra fine slag acts as filler thus also reduces permeability. In this paper mechanical strength development of high strength concrete (M50) with partial replacement of cement by ultra fine slag (alccofine) is carried out. Comparison is done between cubical strength and cylindrical strength of M50 grade concrete using ultra fine slag.
