【摘要】：為提高水泥的水化程度,以特級(jí)礬土、純鋁酸鈣水泥、硅微粉和氧化鋁微粉為原料制備了水泥含量(w)分別為3%、6%、10%的高鋁質(zhì)澆注料。采取空氣中自然養(yǎng)護(hù)、在純凈水中自然養(yǎng)護(hù)、抽真空后在純凈水中養(yǎng)護(hù)三種方式,保存0~20 d后,測(cè)試110℃保溫24 h烘后,800、1 200和1 500℃保溫3 h熱處理后試樣的性能。結(jié)果表明:1)不同的養(yǎng)護(hù)方式對(duì)試樣的常溫物理性能影響不一樣,110℃烘后800℃和1 500℃熱處理后的物理性能差距大,1 200℃處理后的物理性能變化很小;2)水中養(yǎng)護(hù)的試樣烘后常溫強(qiáng)度提高的明顯,水泥量越少,提高的越多。
[Abstract]:In order to improve the hydration degree of cement, the high alumina castable with (w) of 3% and 10% was prepared from super grade bauxite, pure calcium aluminate cement, silica powder and alumina powder respectively. Natural curing in air, natural curing in pure water and curing in pure water after vacuum extraction were adopted. After 0 ~ 20 days of preservation, the properties of heat treated samples were tested after heat preservation at 110 鈩，
