Effect of Steel slag as an additive to Murram for Road Construction in Uganda.

Abstract

This report presents the findings and considerations of my final year project as done at Makerere University. In this report, I present the procedures followed while investigating the effects of using steel slag, a by-product of the steel production industry as a murram additive for road construction purposes. Steel slag presents a huge disposal problem for the steel manufacturing industries in the World and retrospectively, Uganda. This report is presented in six chapters. Firstly, the Introduction outlines the origins of steel slag and how it is produced during the steel making process. It also outlines how much of a problem, it causes and how severe it is. In this Chapter, I also outline the research problem, objectives, significance, justification and scope. In the Literature Review chapter, I summarised already published research regarding the production and physical properties of steel slag. I also outline previous research into the application of the slag in civil construction projects and how they defer with road construction. Lastly, I present the research carried out on its previous use in road construction in other parts of the world The Methodology presents the various procedures used during my research. Most of the procedures used were British Standard, BS 1377. The Results and Result Analysis Chapters present the products of the methodology and their manipulation respectively while the Recommendation and conclusion Chapter is where the deductions from the analysis are drawn. In the final chapter, I outline steel slag’s positive effects on the strength properties of murram and its adverse effects on the water retention properties.
