Natural aggregates, as well as aggregates obtained after the reprocessing of buildings＇ demolition waste, can be used as coarse and fine aggregates. Characteristics of the hardened concrete depend on the raw materials, used for the preparation of concrete mixture, and their characteristics. The objective of the research is to analyse the sources of demolition waste, to describe the reprocessing technology of concrete waste, to investigate the production of the aggregate from the concrete waste, to analyse the main properties of these aggregates -- particles＇ density, bulk density, granulometric composition, hollowness and other properties, as well as to compare the obtained results with the requirements applicable to the aggregates based on natural materials.展开更多

Considering the future, the most important problem recently is how to protect the historical heritage, and how to benefit from it. And as an answer to this question, by benefiting from our cultural background, it is necessary to provide the contemporary requirements and to transfer this attitude to the future generations. Throughout the time, functions may change but old buildings may stay. This situation requires that the old buildings are open to a new contemporary uses. Nowadays, the variations in the functions loaded onto the places we live in are frequently put on the agenda due to the requirements which are continuously changed and developed by social and cultural effects. While faced with this kind of functional variations in order to protect the mean values, the scope of this study is described in a systematically manner as： （1） re-functioning process; （2） adaptation of the new function to the old building; and （3） design concept in the revalorization. The scope will be discussed with many implementations from Turkey and the cases are chosen from the Izmir city.展开更多
