Changing material requirements on construction sites: the example of concrete

© Apur

The dynamic of construction and renovations in Greater Paris remains strong for 2024 and 2030. Almost 36 million m² to be built or rehabilitated are thus scheduled for 2024 and which represent an important stake in the evolution of increasingly carbon-free building materials.

In fact, to prevent the scarcity of certain materials such as natural aggregates and sand, the main raw materials of the construction industry and the resources necessary for the production of ready-to-use concrete, the Apur wished to study with its partners the evolution of material needs for the construction sector and in particular concrete, in view of new emerging construction materials.

The Apur Café will be the opportunity to present:

  • an estimate of the areas to be built in the years to come in the different territories;
  • an estimate of the quantities of materials needed with the current concrete production in the Greater Paris metropolitan area as well as scenarios for the evolution of wood construction from 10 to 30%;
  • and finally, the acceptability conditions necessary to maintain a network of concrete plants in dense urban areas along waterways (Seine and Canals).
