IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Development of a new model sand made from expanded perlite and its characteristics test
Author : XIAO-XIN FEI (1), XING-NONG ZHANG (2) & SI-HE ZHANG (3)
ABSTRACT
In a test of sand physical model, it is very important to select model sand with appropriate physical and kinetic
characteristics. However, most available model sands such as wood, coal sand and plastic sand are not satisfactory in
some ways. In this paper, on the basis of previous research and practice, a new model sand BZY has been successfully
developed. And then, to examine the property of the new type model sand, experiments have been carried out on its
properties, including volume-weight, incipient velocity, settling velocity, repose angle, etc. The experiments show that the
BZY model sand has many merits over others, such as adjustable unit weight, wide rang of particle size, particle shape
similar to natural sand and stable physical & chemical properties. This new model sand can meet various requirements.
It is a kind of sand with appropriate property and has great promotion and application values.
