Abstract
En 中文
The development of unfired high-alumina bricks (UHABs) is of great economic and environmental significance, where bonding performance governs mechanical properties and application. A surprising reinforcement of UHABs bonded by merely 6 wt% rectorite via wet milling process was obtained. The effect of wet milling on the slurry rheological behavior, phase composition and microstructure evolution were investigated to understand the reinforcement mechanism. The results indicated that wet milling could promote the exfoliation of rectorite, increase the dispersity and stability of slurry binders. Reducing the solid content of slurry from 35 wt% to 25 wt% achieved a better refinement and exfoliation effect. Exfoliated sheet-like rectorite formed a face-to-face mechanically interlocked network among bauxite particles, while in-situ gismondine (CaAl2Si2O8·4 H2O) formed after heating at 750 °C bridged rectorite, increasing cold crushing strength by 67% (∼70 MPa). This study aims to provide theoretical assistance for the development of UHABs with satisfied mechanical strength.
