Abstract

Natural sand is not readily available nowadays, and the resources are also exhausting very rapidly. Hence, it is
the time to find some substitute to natural sand. By-products of some industries and artificial sand produced by
crushing machines can be used as an alternative to natural sand. To check the quality of sand, New Zealand sand
flow cone method has been adopted here. This test has been extensively used to measure the performance of sand
and to estimate properties of blend of two or more sands. From this, we can determine flow time, and void content
of oven dried fine aggregate in its loose uncompacted state.
