    Abstract

    Lightweight concrete is used across the construction industry in many different applications. Many different materials have been used as aggregate replacements to enhance the different areas where lightweight concrete can be applied. A commonly used lightweight aggregate replacement includes expanded clay aggregate (LECA). However, to continue the research into different lightweight aggregates this project looks into the use of expanded polystyrene (EPS), because of its many properties the most important being its lightweight properties. This project analyses both EPS and LECA as lightweight aggregate replacements to study both of these materials further. In this project the lightweight aggregates are tested at different replacement levels to look at their compressive strength, flexural strength, sorptivity and thermal conductivity. It is from these results that conclusions can be found to determine if expanded polystyrene would be a suitable aggregate replacement to be used in lightweight concrete. Also in this project the sustainable properties of expanded polystyrene were researched to conclude the sustainability of using expanded polystyrene within construction industry.
