Possibilities of using recycled brick in binders systems with p-clinker content
Tušla, Václav ; Ptáček, Petr (referee) ; Opravil, Tomáš (advisor)
This diploma thesis deals with the preparation binder systems based on Portland clinker and recycled brick. Recycled brick is considered a waste material from construction or production of brick products. This thesis uses finely grounded brick recycled and brick dust, which is produced during final processing of burnt bricks. By incorporating brick dust in alternative system based on Portland clinker could bring ecological and economic benefits. This diploma thesis deals with option using brick dust as pozzolan admixture to Portland clinker, with the aim to prepare and test Portland cement, which is defined in v ČSN EN 197-1. This thesis also deals with possibility preparation of alternative binders based on p-clinker, but those not defined by ČSN EN 197-1. Specifically these are ternary binders with fluid bed ash and binders based on hybrid cements containing sodium sulfate.
Possibilities of utilization of brick-grind-dust in alternative binding systems based on fluidized ash
Tušla, Václav ; Švec, Jiří (referee) ; Opravil, Tomáš (advisor)
This bachelor´s thesis deals with usage of brick-grind-dust in alternative binding systems based on ashes of fluid combustion. Specifically it deals with fly ashes and softly milled bed ashes of brown coal combustion. Primarily thanks of content of free lime, anhydrite and other components, fluid ashes have binding properities. Brick-grind-dust arise in end formation of burned bricks. The aim of thesis is to verify, possibilities to create composite of appropriate abilities with high or even exclusive amount of fluid ashes and brick-grind-waste. The paper also deals with influence of some chemical modifying additive on this alternative systems.
