Ring Crush Testing. Ring crush testing is used to measure the edgewise compression of paper and board materials. A short cylinder of material is inserted into an annular groove and axially loaded to failure. Results are quoted in kN/m. We measure in conformity with International Standard ISO 12192. Short Span Compression Testing (SCT)

The shape of the sand grains from our planet's deserts is too round to be used in concrete (1, 2, 3). This is why we are drawing the last sand resources from natural beaches for making concrete for the everincreasing human demands. Would it not make sense to crush the round desert sand grains in a mill to produce the sand required for concrete?
