Development of recycled concrete mixtures in Luxembourg

Posted on

As one of the partner universities, the University of Luxembourg is actively working on the SeRaMCo project in different aspects: (i) technical features on the design of new concrete mixtures and elements, and (ii) a continuous overview of the market situation in Luxembourg through several stakeholders. More specifically, in the technical aspect of the project (containing three different work packages), the University of Luxembourg’s role is mainly in work package 2 (developing new cement and concrete mixes for use of recycled materials) and in work package 3 (generating and implementing innovative cement and concrete products based on recycled aggregates).

New European Rules on Waste

Posted on

On May 30, 2018, the European Council and the European Parliament approved and signed the Directive to amend the Waste Framework Directive. The document is part of the EU Action Plan for the Circular Economy, which contains several legislation proposals on waste. The text is now waiting to be published in the Official Journal of the European Union, and will officially enter into force 21 days after its publication. The adopted document contains remarkable amendments related to Construction and Demolition Waste of interest for SeRaMCo. Read More

Secondary raw materials in design and architecture

The increasing importance of recycling concrete is undeniable: its production is highly energy consuming, while sand and aggregates are becoming scarcer every day. Since low and medium cost construction is responsible for the majority of cement use, and therefore for the majority of adverse effects, there is a real opportunity to make a difference using secondary resources for the production of concrete precast products.

Identifying perspectives for innovative construction waste recycling

Posted on

SeRaMCo aims at upcycling construction waste such as concrete, bricks, tiles and ceramics to turn them into valuable secondary raw materials for the production of concrete precast products. Such products should eventually be equal in terms of quality and price to those made from primary raw materials. New cutting-edge technologies are required to innovatively recycle construction site waste and to evaluate the general feasibility and relevance based on prototypes. Beton-Betz’s involvement within SeRaMCo focuses mainly on: - Developing innovative recycling methods for the end-product plants; - Developing new and optimized mixed-concrete formulas using recycled gravel and sand; - Selecting suitable types of pre-cast concrete to apply the new formulas.

Recycling of construction and demolition waste in cement

Posted on

Treatments of construction and demolition waste (CDW) produce aggregates with sizes ranging from few micrometers to several centimeters. Because of the high water absorption and impurities in the finest fraction (grain size below 2 mm), recycled sands can hardly be used as secondary raw materials for concrete production. Therefore, in the framework of the SeRaMCo project, University of Lorraine and the cement manufacturer Vicat use these fine recycled aggregates as raw material for the production of cement.

Technical aspects of CDW recycling

Posted on

The University of Liège (Wallonia, Belgium) is working on the technical aspects of recycling sands and aggregates from construction and demolition waste (CDW). Their analyses focus on the best processes for treating CDW with regard to three points: the washing process, fragmentation, and the compressive strength and durability of mortar and concrete. The ultimate objective is to position recycled aggregates and sands as a true alternative to primary raw materials in construction. Read More
