Reactivity of ultrafine powders produced from siliceous rocks
Quartz and basic or devitrified volcanic rocks, which otherwise were not suitable as sources of pozzolan, acquire high pozzolanic reactivity when ground to ultrafine powders; in case of such grinding all siliceous materials show same pozzolanic properties, regardless of whether their powders would be classed as pozzolanic, weakly pozzolanic, or nonpozzolanic when ground to usual fineness.
