Is magma viscosity directly related to its silica content? Does Mount Vesuvius have volcanic ash or pyroclastic flow? What does pyroclastic flow consist of? How long does it take for a volcano to form? What type of eruption produces pyroclastic flow?
There is a wide variation in the chemical properties of fly ash and GGBS.Fly ash is low in calcium oxide content but rich in silica and aluminawhile GGBS is relatively high in calcium oxide. The combination of these two materials can be more beneficial when used as a stabilizing agent than...
also could be attributed to the improved interfacial compatibility due to the incorporation of surfactants (Span 80 and Tween 80), which acted as a coupling agent. Furthermore, the silica incorporated in the WF could compensate the negative effect of paraffin on thermal stability of the composites...
