【摘要】：测试了不同种类石灰制备的(传统)糯米灰浆的表面硬度、抗压强度、耐冻融性等性能,观察了不同种类石灰及其制备的糯米灰浆的微观形貌,探讨了石灰种类对糯米灰浆性能的影响机理.结果表明:采用分析纯氧化钙和工业氧化钙制备的糯米灰浆的抗压强度、表面硬度和耐冻融性均优于采用分析纯氢氧化钙和工业灰钙粉制备的糯米灰浆,其中,采用分析纯氧化钙制备的糯米灰浆的抗压强度等性能最好.在砖石质不可移动文化遗产保护实践中,建议采用分析纯氧化钙制备糯米灰浆.氧化钙陈化过程中形成的较小氢氧化钙板状晶粒是采用氧化钙制备的糯米灰浆微观结构细密的主要成因.正是由于采用氧化钙制备的糯米灰浆的微观结构细密,因此该类糯米灰浆的抗压强度等性能良好.
[Abstract]:The surface hardness, compressive strength and freeze-thaw resistance of the (traditional) glutinous rice mortar prepared with different kinds of lime were tested, and the microscopic morphology of different kinds of lime and its prepared glutinous rice mortar were observed. The influence mechanism of lime type on the properties of glutinous rice mortar was discussed. The results showed that the compressive strength of glutinous rice mortar prepared by analyzing pure calcium oxide and industrial calcium oxide was analyzed. The surface hardness and freeze-thaw resistance of glutinous rice mortar prepared by analytical calcium hydroxide and industrial lime calcium powder were better than that of glutinous rice mortar. The compressive strength and other properties of glutinous rice mortar made of pure calcium oxide are the best. In the practice of protecting the unmovable cultural heritage of masonry, It is suggested that the preparation of glutinous rice mortar with analytical pure calcium oxide. The small plate grain of calcium hydroxide formed during the aging process is the main cause of the fine microstructure of the glutinous rice mortar prepared with calcium oxide. It is precisely because of the use of oxygen that the fine microstructure of the glutinous rice mortar is caused by the use of oxygen. The microstructure of glutinous rice mortar prepared by calcium is fine, Therefore, this kind of glutinous rice mortar has good compressive strength and other properties.
