<p>A process for the production of a clinker having a ²-C2S content of > 60% by weight, a C4A3$ content of < 5% by weight and a C3S content of < 15% by weight, comprising the stages of
i) preparing a particulate mixture comprising:
- powder having an SO 3 content of between 2% and 10% by weight obtained from firing of the fine fraction of waste concrete having a particle size of less than 500 µm in a quantity of between 20 and 90% by weight at a temperature of between 1150 and 1350°C, and
- limestone in a quantity of between 10 and 65% by weight, and
ii) firing the mixture at a temperature of between 1150 and 1350°C.</p> |
