添加無機聚合物黏土磚材料之開發研究
Development of Clay Bricks Adding Geopolymer
摘要
傳統黏土磚的主要原料是黏土，經攪拌成可塑性，用機械擠壓成型成為磚坯，再經風乾後送入窯內，在900 ~ 1000℃的高溫下窯燒而成磚塊。普通黏土磚之抗壓度約為300 kgf/cm2。無機聚合物則為近年來在取代水泥甚至環氧樹脂等粘接材料方面，有相當程度表現之新材料。本研究則嘗試在粘土中添加一定比例之無機聚合物，以配比、煆燒溫度與時間為參數，期望能在經由較低溫之煆燒，即可達到或增加粘土磚之強度，以節省能源。研究結果顯示，當無機聚合物中的高嶺土和黏土的比例為1：1，在常溫時抗壓強度即可達383 kgf/cm2。如再經過300 ℃一小時的煆燒，抗壓強度則提升為430 kgf/cm2，增加約12.3%。當二者的比例為1：6時，常溫抗壓強度為23 kgf/cm2，經高溫1000℃十二小時煆燒後之強度提升為213 kgf/cm2，增加約826%，已接近紅磚抗壓強度，而其煆燒熱能則遠低於傳統磚窯，顯示節能減碳的潛力。

The raw material of the traditional clay bricks is clay. They are manufactured by mixing and compacting into blocks, and after drying out then put into a 900 ~ 1000℃ brick furnace for few days. The compressive strength of regular clay bricks is about 300 kgf/cm2. A recent developed material, namely geopolymer, has performed quite well in replacing adhesive materials such as cement and epoxy. The present research is attempting to add a certain percentage of the geopolymer into clay. It is expected that the temperature and the duration of the furnace can be reduced to achieve or increase the strength of clay brick in order to save energy. The results showed that when the ratio of kaolin used in the geopolymer and clay was 1:1, the compressive strength could be up to 383kgf/cm2 even under room temperature. Further put it under temperature of 300 °C for one hour, the compressive strength was increased to 430 kgf/cm2, the increment is approximately 12.27%. While increase the ratio to 1:6, the compressive strength was 23kgf/cm2 under room temperature, and calcinated 12 hours under temperature of 1000℃, its compressive strength jumped to 213 kgf/cm2, with a increment of 826%. It is seemed that the heat energy required is much lower than the traditional clay bricks, revealing the potential of saving energy and carbon dioxide..
