Paperback. Condición: New. Print on Demand. This book delves into the standardization of the No. 200 Cement Sieve, a crucial tool for determining the fineness of cement. After an investigation by the author, the book concluded that the existing specifications for the sieve were inadequate. The findings highlight that the current method of certification, based on measurements of wire diameter and mesh, does not provide a reliable indication of sieving values. Through a series of cooperative sieving tests, the necessity for a revised specification is emphasized. The author proposes a new optical test that addresses the limitations of the present method and explores various materials as potential standard samples for sieve calibration. The significance of this book lies in its thorough analysis of the No. 200 Cement Sieve, offering insights into its standardization and performance, ultimately contributing to improved accuracy in cement fineness determination.
