Re-use of construction and demolition waste within the local building industry

Abstract

The quality of the environment is highly dependent on the construction industry. Hence, the inclusion of non-renewable materials must be kept to a minimum at all costs. Consequently, this dissertation investigates the potential use of substitutes to the natural hard/soft stone used currently for the construction of urban development. The study is mainly concerned with the construction waste found in land-filled sites rather than demolition waste which involve processes, necessary for the separation of different materials. This dissertation also addresses the standards which regulate waste management, including E.U. standards. The primary objective of this study is to consider the use of several proprietary lime and cementitous based binders which could be employed in the mix design production of re-constituted stone blocks and products. By means of test programme, several mixes were produced and their physical performance and cost was compared. The use of re-constituted stone for nonstructural/architectural purposes is also discussed.
