Elizabeth, along with her younger brother, Lawrence, is a virtual slave living on a farm owned by the Forsythes. She depends upon Charles Forsythe, her cruel master, for everything. He extends his hold over her by raping her and as a result she becomes pregnant. It is while she is in hospital giving birth that she glimpses a life that is possible beyond her miserable existence, mainly because of the kindness shown to her by a young white male nurse.
Concrete is at something of a crossroads: there are many opportunities and some threats. For those opportunities to change into beneficial practice, engineers, material scientists, architects manufacturers and suppliers must focus on the changes that are required to champion concrete and maintain its dominance within the global construction industry. The Concrete Technology Unit (CTU) of the University of Dundee organised this Congress to address these changes, under the theme Global Construction: Ultimate Concrete Opportunities, 5-7 July 2005. The three-day International Congress consisted of ten Events. "Use of Foamed Concrete in Construction" forms the Proceedings of Event 6 and deals with issues such as materials, properties and production characteristics, specification for foamed concrete, applications and case studies.About the Authors: Professor Ravindra K Dhir is founding Director of the Concrete Technology Unit (CTU) at the University of Dundee.
