Laser granulometry: A comparative study the techniques of sieving and elutriation applied to pozzoianic materials

Abstract

Laser granulometry is a rapid method for determination of particle size distribution in both dry and wet phases. The present paper, diffraction technique by laser beams is an application to the granulometric studies of pozzolanic materials in suspension. Theses granulometric analysis are compared to those obtained with the Alpine pneumatic-siever and Bahco elutriator-centrifuge.
