Research of interface between quartz and non quartz mould materials grains and geopolymer binder
Skřivánková, Vendula ; Burian,, Alois (referee) ; Cupák, Petr (advisor)
Presented thesis deals with monitoring of the properties of the interface between opening materials and geopolymer binder using three quartz and four non quartz opening materials. There is observed mainly the type of destruction of connective bridges. The theoretical part of the thesis briefly summarizes commonly used methods in foundries and monitors experience with implementation of geopolymers in different foundries. The practical part monitors shape of the grains of the chosen opening materials. There are writed down the results from the measurement of the bending strength and workability and there is observed the type of destruction of connective bridges.
