1. Introduction. The possible usage of sea sand as mixing fine aggregate in concrete production is gaining increasing interest due to scare river sand resources [1].Some studies have shown that the mineral composition, crush value, and fineness modulus of sea sand are similar to those of river sand [2], and it has a certain machinability [[3], [4], [5]].

Ring Crush Test Determining the Ring Crush Strength
The ring crush test is similar to the short-span compression test in that the strength of the liner or fluting is measured both in the machine direction and perpendicular to it. It is important that force application to the specimen is exactly perpendicular during these tests. The results of this test are also highly dependent on proper specimen preparation.
