Abstract


The advances in laser technology have permitted the development of numerous applications, in particular diffraction spectrometry by laser beams for the determination of the distribution curve of the particle sizes of different materials; this permits one to obtain the distribution of particle size in both wet and dry materials. In the present paper a brief description of the technique and its principles is offered. The results obtained with different materials-limestone clay, gypsum, Portland cement and siliceous materials are given.
