Dry pluviation is one of the most widely used methods to prepare granular soil samples at target void ratios for laboratory testing. This study experimentally investigates packing characteristics of binary sand mixtures deposited by dry pluviation with various mixing ratios and particle size ratios. Two theoretical models for estimating void ratios of binary mixtures are critically reviewed ...

Fine coal dust will also reduce the overall permeability of the sand. Coal dust levels in green sand vary from 2 or 3% for small castings to 7 or 8% for heavy section castings. Too much coal dust can give rise to gas holes in the castings or misruns. Coal dust must be stored dry to prevent the risk of fire.
