Deskripsi

A variety of structures are constructed in Pakistan using different construction materials. Cement-lime mortar is widely used worldwide but not commonly used in Pakistan. Cement-lime mortar is a technique that doesn’t require water for its curing purposes. Structural durability, economy and energy efficiency are the basic parameters of a modern construction. In order to attain these parameters, several building construction techniques and environment friendly materials have been introduced. One such building technique to save energy, material and to resist the applied loads is ‘Chinese Bond Brick Masonry (CBBM)’. The structural properties, construction cost, energy efficiency and thermal comfort is compared by testing English and Chinese bond masonry prisms. Chinese bond walls performed excellent in saving materials, less penetration of external heat waves and resistance against compressive and lateral loadings. In this study, it has been tried to explain the importance of CBBM methodology along with construction details. It also provided some comparative calculations to highlight the requisite strength against failure of structure, durability and cost savings that can be achieved against the conventional brick masonry. Compressive strength of Chinese bond prisms did not increase over time but shear and diagonal compressive strength increased. Thus, it is found that compressive strength is related to strength of brick while shear strength, representative of masonry unit, was more related to mortar strength. It is also noted that addition of lime to mix increased the strength of mortar after 28 days and water require for curing of masonry structures can also be saved efficiently.
