Though the architecture mortar or plaster has many different compositions and of a great varieties, the characteristics and the right mix proportion are not available. In order to rehabilitate the historical monuments, it is thus necessary to study suitable mortar for different applications.
The materials used in this study include sand, clay, lime, plaster of Paris, syrup, carambola juice, oyster shell, and tung oil. The results show that the carambola juice and lime can reduce the shrinkage; oyster shell can increase the early strength; and tung oil can increase waterproof ability, while syrup may reduce the water requirement and increase strength.
