Keywords: Cupola furnace slag, compressive strength, normal aggregate concretes, slag aggregate concrete


The compressive strength of the concrete designed using blast cupola furnace slag and granulated cupola slag as a coarse aggregate and partial replacement for cement was investigated. A series of experimental studies were conducted involve concrete production in two stages. The first stage comprised of normal aggregate concrete (NAC) produced with normal aggregates and 100% ordinary Portland cement (OPC). Meanwhile, the second stage involved production of concrete comprising of cupola furnace slag an aggregates with 100% ordinary Portland cement (OPC) and subsequently with 2%, 4%, 6%, 8% and 10% cementitious replacement with granulated cupola furnace slag that had been grounded and milled to less than 75 µm diameter. The outcomes of compressive strength test conducted on the slag aggregate concrete (SAC) with and without granulated slag cementitious replacement were satisfactory compared to normal aggregate concretes (NAC).

Author Biography

Stephen Adeyemi Alabi, The Federal University of Technology, Akure, Nigeria

I am presently a Research Assistant and lecturer in the Department of Civil Engineering of the Federal University of Technology, Akure, Nigeria, where I obtained my Master of Engineering degree in Structural Engineering in 2012 with Distinction. Also, I obtained my B.Eng degree in Civil Engineering at the Federal University of Technology, Akure, Nigeria in 2008 with first class honours as the best graduated student of my set. After my graduation I have been working as an Assistant lecturer in the same Department I graduated from, assisting in teaching of civil engineering materials, design of reinforced concrete structures and Structural Analysis and, this is evident in my having the highest scores in civil engineering materials and design of reinforced concrete structures during my undergraduate and postgraduate days. With my prior knowledge of the basic principles of Civil Engineering materials, Design of reinforced concrete structures, Structural dynamics, Structural Mechanic, Design of Structural and Structural Analysis, my working currently as a Research Assistant, zeal to research, composure, intelligence and academic prowess.


My main research interest is in use of innovative materials in building industry, risk analysis and strategies for management of engineering systems, numerical modeling with computer application in structural engineering. The  research topics include, behaviour of geopolymer concrete with recycled concrete aggregate, physico-mechanical properties of  concrete produced with different percentages of cigarette butts, behavior of granulated cupola furnace slag based geopolymer concrete at elevated temperature, probabilistic description of the progressive failure of a RC building frame under differential settlement, probabilistic model for compressive strength of a concrete using Akure pit-sand as fine aggregate, optimum mix design for minimum concrete strength requirement using pit-sand as fine aggregate, material-based ultimate moment of resistance of a reinforced concrete section.
