Abstract
Cements and concretes are so-called "mass-produced" construction materials, because they are used almost universally, and therefore in large masses or volumes. Sustainable access to mineral resources is therefore a key issue for the sustainability and development of the construction sector. This sustainability of resources also extends to fuels, as cement production is an energy-intensive industry, both for the firing of raw materials and for grinding, without which production would not take place.
After recalling the essential differences between cement and concrete, and the production processes for both materials, we'll look at the key stages in the processes that enable us to introduce and apply the principle of parsimony in cement and concrete production, and thus envisage sustainable construction. Energy consumption will be dealt with briefly, given its place in sustainable development and its intensity in the industrial context.
The conclusion will be a natural plea for the circular economy in general and recycling in particular.
