Láser granulometry: A comparative study the techniques of sieving and elutriation applied to pozzolanic materials

摘要

[EN] Láser granulometry is a rapid method for\uddetermination of partióle size distribution in both dry and wet phases.\udThe present paper, diffraction technique by láser beams is an application to the granulometric studies of pozzolanic materials in suspensión.\udTheses granulometric analysis are compared to\udthose obtained with the Alpine pneumatic-siever and Bahco elutriator-centrifuge.
