Abstract

Korean traditional clay bricks are made in a unique way such as "carburizing heat-treatment", but little is known about the characteristics of the traditional brick-based masonry. In this study, the mechanical properties of the traditional masonry were experimentally investigated with the binder type and aggregate contents of mortar as test parameters. First of all, the material properties of masonry components were identified. The strength of brick was 44.4 MPa, while that of the mortar varied significantly depending on the test parameters. However, the prism compressive strength of the masonry was not consistent with the mortar strength, since the strength difference among the samples was insignificant. More importantly, it is challenging for Korean traditional masonry to have a high level of bond strength because the surface of the clay brick is coated with carbon during the carburizing process. Nevertheless, the use of hydraulic cement instead of air lime is effective in improving the bond strength under the condition that mechanical bond such as friction or interlocking is guaranteed first. However, natural hydraulic lime showed negative effects and is therefore not recommended as a material for the traditional masonry.
