<p>A process for producing a concrete additive to improve the flow properties thereof involves: a) selection of sepiolite mineral by probing before extraction, b) weathering to reach a humidity between 30% and 40%, c) reduction to a particle mesh size of 3 mm, d) rotary drum drying at 75 DEG to 80 DEG C to reach humidity content of 13% to 15%, and e) sieve screening until 95% of the particles are between 125 and 437 microns. s</p> |
