By employing this method, the hydration process of each sample can be quantified. For instance, in the case of the reference group sample, the initial hydration stage lasted approximately 0.8 h, indicating the reaction of calcium sulfoaluminate hydrate in CSA with gypsum to form ettringite.Huge avalanches of searing hot ash, gas, and pumice roared down the flanks of Mount Pinatubo, filling once-deep valleys with fresh volcanic deposits as much as 660 feet thick. The eruption removed so much magma and rock from below the volcano that the summit collapsed to form a large volcanic depression 1.6 miles across."
