摘要：以粒化高炉高钛矿渣粉为主要原料，水玻璃为激发剂，铝粉为引气剂，制备了碱激发高钛矿渣免烧陶粒。试验发现单一使用高钛矿渣粉制备的陶粒保气量不足、堆积密度较大，提出添加少量粉煤灰或固硫灰对其进行了改性，研究改性前后陶粒性能，利用XRD、SEM等手段探讨了陶粒矿物组成和微观结构。试验结果表明，掺入适量的粉煤灰或固硫灰，体系浆体黏度提高，保气量改善，能制备出容重更小的免烧陶粒。 Abstract: Sinter-free lightweight aggregates（SLWA） have been prepared by using titanium slag as raw material, sodium silicate water glass as alkaline activator and aluminite powder (AP) as air-entraining agent. And the relatively high bulk density of SLWA was observed, due to the low viscosity and gas preservation of pastes when titanium slag was used alone. Therefore, fly ash and circulating fluidized bed combustion fly ash (CFBC) were used to improve properties of SLWA.And the XRD and SEM tests were used to study the mineral composition and microstructures of prepared SLWA. The results showed that the viscosity and gas preservation could be improved. And the SLWA with lower bulk density has been obtained.
