NXT Concrete<\/h1>\n\n\n\n

Circular concrete<\/h3>\n<\/div>\n<\/div>\n\n\n\n
\n

In a world where the construction industry is responsible for a significant proportion of CO2 emissions, NXT Concrete offers a solution that is both sustainable and economically attractive. After all, why use traditional concrete if you can do it sustainably? We therefore produce and supply circular concrete, which can be used in a variety of applications such as foundation components, street furniture and other innovative building solutions. Not more expensive, but more sustainable! <\/p>\n<\/div>\n<\/div>\n\n

What is NXT Concrete?<\/strong><\/h2>\n\n\n\n

At NXT Building, we believe in a future in which sustainability is central. NXT Concrete circular concrete is an important step in that direction. Our concrete is made from recycled building materials, such as debris from demolition projects. The goal is to extend the life cycle of concrete and reduce dependence on primary raw materials. By doing so, we reduce our ecological footprint and contribute to the circular economy. <\/p>\n\n\n\n

How is it made?<\/strong><\/summary>\n

We produce circular concrete by reusing old concrete remnants and secondary raw materials. We do this with our specially developed NXT Separator<\/a>: <\/p>\n\n\n\n

    \n
  1. We start demolition, or urban mining. Here we are using electric equipment. <\/li>\n\n\n\n
  2. The harvested debris then goes into a traditional crusher for pre-crushing. This crusher reduces the existing concrete blocks to a size suitable for the NXT Separator. <\/li>\n\n\n\n
  3. The material goes into the NXT Separator, which ensures that all pieces are thoroughly crushed. This produces clean gravel, sand and filler. <\/li>\n\n\n\n
  4. With the gravel, sand and filler obtained, we produce new concrete, which is of higher quality (upcycled) than the original harvested concrete. The only thing we add to this is a minimal amount of cement in the concrete mix. We use less cement for this compared to regular concrete. <\/li>\n\n\n\n
  5. Finally, the circular concrete is ready for loose dumping!<\/li>\n<\/ol>\n<\/details>\n\n\n\n
