【導(dǎo)讀】和水玻璃溶液激發(fā)制備得到的。在制備過程中在模具中對反應(yīng)產(chǎn)物施以4MPa壓。力并放在65℃恒溫箱中處理10小時后對材料的抗折強度、抗壓強度和表觀密度進行系統(tǒng)測量。高嶺土地質(zhì)聚合物的機械和化學性能的影響。時間對抗折強度影響很小然，而對抗壓強度和表觀密度幾乎沒有影響。X射線衍射和紅外光譜。高嶺土煅燒過程中空氣中的水和少量惰性成份。地質(zhì)聚合物中非晶相的含量隨著氫氧化鈉濃度。掃描電子顯微鏡的結(jié)果表明制備的地質(zhì)聚合物維持了偏高嶺土微粒的層狀結(jié)構(gòu)，所以認為地質(zhì)聚合物反應(yīng)主要發(fā)生在偏高嶺土顆粒的微晶表面上。這種材料的強度數(shù)據(jù)顯示這種基于偏高嶺土的膠體反應(yīng)會使得建筑材料具備良好。由反應(yīng)進程可見，鋁硅酸鹽和催化劑兩大因素直接影響最終產(chǎn)物。將按照上述比例制成的催化劑加入偏高嶺土粉末中，并攪拌5分鐘。圖1顯示的是在空氣中放置7天的偏高嶺土和反應(yīng)產(chǎn)物的X射線衍射花樣。XRD衍射圖像表明偏高嶺土有些成分如石英和莫來石等始終未參與反應(yīng)。
