Abstract
In the process of river sand mining management,it is often encountered to convert the measurement unit of river sand and gravel from tons to cubic meters.At present,there are no relevant documents in China that clearly stipulate the conversion ratio.The standards for converting measurement units vary in different regions,and are ba-sically determined based on personal experience.Accumulated density inspection tests and analysis were conducted for river sand and gravel under different environmental conditions,to provide reference for determining the conver-sion ratio of the measurement units of river sand and gravel from tons to cubic meters.关键词
