Abstract

Among the available procedures for obtaining reconstituted laboratory sand specimens, pluvial compaction appears to best simulate the natural processes leading to formation of sand deposits. Although widely used for a long period of time, effects of some components of the specimen preparation equipment (sand rainer) on the relative density of the specimen formed have not been comprehensively studied. This paper presents the results of an investigation aimed at studying these effects. The results obtained are used to provide a guide-line for design of a sand rainer.
