Description:

EuroLightCon project is funded by the European Union under the Industrial & Materials Technologies Programme (Brite-EuRam III) Contract BRPR-CT97-0381, Project BE96-3942.

Established in 1997, EuroLightCon is a three-year project that involves close cooperation between Norwegian, Dutch, German, British, Spanish and Icelandic companies, universities, research institutes and government agencies. The project aims to further develop lightweight concrete technology by testing new aggregates that utilize waste products, by identifying new areas of use for LWA concrete, and by drawing up rules for the dimensioning of reliable structures.

It is the objective of the EuroLightCon-project to develop a reliable and cost effective design and construction methodology for structural concrete with LWA. The proj ect addresses LWA manufactured from geological sources (clay, pumice etc.) as well as from waste/secondary materials (fly-ash etc.). The methodology shall enable the European concrete and construction industry to enhance its capabilities in terms of cost-effective and environmentally friendly construction, combining the building of lightweight structures with the utilisation of secondary aggregate sources.

The major research tasks are:

1. Lightweight aggregates: The identification and evaluation of new and unexploited sources specifically addressing the environmental issue by utilising alternative materials from waste. Further the development of more generally applicable classification and quality assurance systems for aggregates and aggregate production.

2. Lightweight aggregate concrete production: The development of a mix design methodology to account for all relevant materials and concrete production and in-use properties. This will include assessment of test methods and quality assurance for production.

3. Lightweight aggregate concrete properties: The establishing of basic materials relations, the influence of materials characteristics on mechanical properties and durability.

4. Lightweight aggregate concrete structures: The development of design criteria and rules with special emphasis on high performance structures. The identification of new areas for application.

At the time the project is being performed, a Working Group under the international concrete association FIB (the former CEB and FIP) is preparing an addendum to the CEB-FIP Model Code 1990, to make the Model Code applicable for LWAC. Basis for this work is a state-of-the-art report referring mainly to European and North-American Standards and Codes. Partners in the project are also active in the FIB Working Group.
