Materials containing asbestos, road rubble containing bitumen or tar, construction materials containing gypsum, and mineral insulation materials are explicitly excluded from the input materials for the production of recycled aggregates.
Quality branded recycled aggregates: REMEXIT
The REMEX success story began in the 1970s with innovative recycling solutions for road demolition waste and construction waste. In 1990, shortly after the German reunification, REMEX was commissioned with the recycling of around 250,000 tonnes of reinforced concrete elements from the deconstruction of the Berlin Wall. Today, as one of the largest manufacturers of sustainable construction materials, our processing technology is synonymous with particular expertise in the production of secondary materials. Our recycled aggregates, which we market under the REMEXIT brand, have been well known in the construction industry for decades.
Which materials form the basis of recycled aggregates?
In according regulations, the permissible input materials for the production of recycled aggregates and their subsequent reuse are defined in detail. In principle, the following materials, for example, can be processed into recycled aggregates:
- mineral construction and demolition waste (consisting e.g. of concrete, bricks, ceramics)
- road rubble
- mineral content of construction waste
- fractures or faulty batches resulting from the production of mineral construction materials
- excavated soil with a mineral content of more than 10 % by volume
Production process, areas of application, quality assurance
The use of recycled aggregates is defined by structural and ecological specifications. The better the material qualities of the recycled aggregates, the greater their application possibilities.
Material with many advantages
It is not uncommon for recycled aggregates to have advantages over natural aggregates in terms of physical constructive properties. Crushed concrete and mortar, for example, often lead to higher strength and stability in the overall mix, even in comparison with natural construction materials.
For environmental reasons, the material cannot be used everywhere. However, in most cases, application is straightforward because conditions of use are clearly defined. Economic efficiency is often the decisive argument for the use of recycled aggregates.
We produce over two million tonnes of REMEXIT branded recycled aggregates every year, which represent an important business area for our company. Find out more on our dedicated website.
