The rapid worldwide growth of the construction industry during recent decades has resulted in an enormous increase in the global production of Construction and Demolition Waste (CDW), placing an enormous strain on the environmental. The industry urgently needs to implement changes to economic policy and decision-making criteria to address this issue and to safe-guard the environment.
CDW contains a complicated combination of bulky and heavy materials such as concrete (40%–67%), wood, asphalt, gypsum, metals, bricks, glass, and plastics
There is currently 850 million tons of CDW in Europe (31% of total waste generation)
The global cement industry produces 1.6 billion tons of CO2 annually (8% of total emissions)
There is 39 kg of construction waste in every square metre of building
The recent financial crisis impacted on the building and construction (B&C) sector with increased unemployment and increased pressure on sub-sectors such as construction materials, distribution channels and logistics
EU targets set for 2020 and 2050 (reducing CO2 emissions by 80-95%) create an increased need for efficient, affordable and deep refurbishment by a factor of 2 to 3 times the current rate
Deep refurbishment is difficult due to the level of time and capital investment required, and inadequately optimised technologies
In the frame of GREEN Instruct project, a variety of products (geopolymers, fibers, aggregates, additives) are developed, based on different CDW streams (bricks, concrete, glass, plastics, wood, aluminum). All raw materials and final products are characterized as far as composition, structure and properties are concerned. In order to handle all these data, during the GI project, a measurement database has been built. According to the database design, each sample will be sorted by measurement technique, while each technique will be sorted by partner. The Measurement Database is divided in two parts:
The folder Measurement Conditions, reporting the instrumentation and the measurement conditions (one file per partner).
Contains the raw measurement files sorted by material (first level) and by measurement (second level).
The data base will be periodically updated until the end of the project and is open access to other projects and researchers. The measurement results are also available upon request at kakali@central.ntua.gr
