Volcanic ash (VA) is a natural resource whose use in cementitious materials has been extensively studied in the last thirty years. The pozzolanic activity makes the volcanic product suitable for use as supplementary cementitious material in concrete. However not all ashes possess this reactivity in their natural state.

Volcanic ash and human complement
Life Sciences, 1981Abstract Volcanic ash shows slight conversion of C3 with little effect on hemolytic complement in vitro . No conversion of the alternative pathway component Factor B was noted. Complement activation should play only a minor role in any acute respiratory response to inhaled ash.

Volcanic ash samples collected from a variety of recent eruptions were studied, using petrography, chemical analyses, and scanning electron microscopy to characterize each ash type and to relate ash morphology to magma composition and eruption type. The ashes are best placed into two broad genetic categories: magmatic and hydrovolcanic (phreatomagmatic)
