SeRaMCo: Secondary Raw Materials for Concrete Precast Products
The construction sector is the most resource intensive industrial sector in the EU. It uses around 50% of the available primary raw materials, hence exhausting the natural resources, degrading environment and generating high costs to the business operators.
Although there is potential for the use of secondary raw materials from construction and demolition waste (CDW), this is far from becoming mainstream in Europe. For the time being, the sector uses only 4% of the recycled construction and demolition waste (CDW), although CDW represents the largest waste stream in the EU, accounting for 1/3 of the overall European waste.
Against this background, this situation is not dire in the whole of Europe. Some North-Western Europe (NWE) countries, namely Germany, France, Belgium and the Netherlands are leading the way in recycling CDW. Depending on the individual country, these rates range from 70-95%.
However, although waste recycling rates in NWE are impressive, business operators from the construction sector are still faced with challenges in placing their recycled products on the market. This is primarily due to the fact that there is still no niche market for concrete products made from the recycled materials. The lack of a niche market is accompanied by the lack of a clear-cut legislative framework in certain NWE states and inability to make precise cost estimations reflecting both social and economic costs of the production.
To make the most out of the available resources, SeRaMCo aims to replace primary raw materials with the high-quality materials recycled from CDW, e.g. concrete, bricks, tiles and ceramics (CBTC), in production of the cement and concrete products for use in NWE. To attain this goal, the project will:
analyse and improve sorting of CDW, as a precondition for successful recycling;
develop and test new concrete mixes and technologies for the production of concrete precast products (CPPs) made from the recycled CBTC;
establish a market niche for CPPs, leading to the economic advantages for the CPP producers and generating new jobs in the construction sector.
SeRaMCo’s expected outputs are cement and CPPs from up to 100% recycled aggregates, comparable to conventional products both in terms of costs and quality, and ready for commercialization in NWE.
Prior to rolling-out across NWE and Europe as a whole, SeRaMCo will test its end-products in 3 pilot areas, namely City of Seraing (Belgium), City of Saarlouis (Germany) and Region of Moseille (France). Following the testing phase, previously developed business models, supporting the supply chain of the new market niche and establishing ecosystem with stakeholders active in the field, will be put in place.

A new mix design methodology for recycled aggregate concrete by combining experimental and numerical approachesPosted on
An important step towards a sustainable development in the concrete industry and management of construction waste is to use recycled aggregates (RA) as a viable alternative to the natural one. However, how to formulate and optimize the concrete mixture made of recycled aggregates at an acceptable price and quality is still a question mark. The major difficulty is due to the variability of the aggregate properties, and the lack of a robust methodology able to accurately evaluate the mechanical performance of the recycled concrete.

Recycled Aggregates (RA) from Construction and Demolition Waste (CDW) contain natural aggregates, hardened cement paste but also masonry, plaster, etc. Part of these recycled aggregates are hardly suitable for concrete production due to their water absorption (cement paste porosity, clays) and reactivity (sulphate or alkalis release, etc.). RA incorporation in Portland cement raw meal is a possible way to use these recycled aggregates and consequently avoid landfill. Read More
One of the objectives of the project SeRaMCo (Secondary Raw Materials for Concrete Precast Products) is the development of concrete mixtures for precast elements for structural and non-structural purposes, especially pavement elements. Read More
Within the SeRaMCo project, the first industrial tests on cement and concrete mixes are starting. Read More
‘Circular Netherlands in 2050’ – An Impetus for Secondary Raw Materials in the Construction IndustryPosted on
Construction is an important sector in the Dutch economy, accounting for almost 7% of the Gross Domestic Product and providing employment for 458,000 people. Every year the Dutch construction sector consumes 250 million tons or 50 percent of raw materials in the Netherlands. At the same time it produces 23 million tons of demolition waste of which 97% are recovered, mostly for use under the road surface. Read More
Research which aims at having long-term societal impact not only needs knowledge and curiosity but also business potential. In this sense, an important part of the Work Package “Long-term effects” of the European INTERREG project SeRaMCo – Secondary Raw Materials for Concrete Precast Products – is the development of business models.

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).

The University of Luxembourg has the pleasure to invite you to the mid-term conference of the European project SeRaMCo: “Secondary Raw Materials for Concrete Precast Products”. Initiated in 2017 with 10 European partners, SeRaMCo aims to replace primary raw materials with the high-quality materials recycled from construction and demolition waste. The mid-term conference will be a great opportunity to show first results of the project SeRaMCo and to discuss the subject with invited expert speakers.
