Microstructure of alumosilicate polymer
ASP microstructure (silica sand bound at points by alumosilicate precursor), moulding sand mixture, fracture surface.
ASP structure (fly ash), polished specimen, BSE image.
Metakaoline.
ASP microstructure (fly ash, ground granulated blast furnace slag), polished specimen. The amorphous ASP substance contains non-reactive coarse slag parts.
Detail of amorphous ASP (fly ash).
ASP structure (fly ash as raw material), fracture surface. The microstructure shows, apart from an amorphous ASP phase, remains of non-reactive fly ash (predominantly its ferrous part) plus pores (macro, micro and nano pores).
