The making of a building structure by laying individual units and binding them together using mortar can be defined by the term masonry. The individual units themselves can also be referred by the term masonry. Brick, stone, marble, granite, cast stone, lime stone, glass block, concrete block, stucco, cob, tile and travertine are the most basic materials for the construction of masonry in MD0. It is simply a very high durable type of construction. The quality of mortar, materials and workmanship has a very significant role to play on the durability of the overall construction of masonry. In industrialized countries, concrete blocks and bricks, find a major application. In Washington, DC, masonry is very common for building walls, retaining walls and buildings. Concrete blocks, those having hollow cores provide good compressive strength. When cores are filled with steel reinforcement, then tensile strength and lateral strength both can be increased. Masonry like every field has various advantages as well as disadvantages, as follows: because of the use of bricks, stones etc the thermal mass of the structures increases and thus ability to resist fire increases. Many types of masonry activities don’t require painting and hence saves a lot of money.
The structures are better projectile resistant such as protection from strong winds, hurricanes etc. Masonry structures are in fact an easy prey to frost damage and thus may lead to degradation. As the structures are heavy, therefore problems like settling and cracking may easily occur. In order to avoid this, a strong foundation is made using reinforced concrete. And a precise amount of skilled labour is required for masonry construction.
The masonry structures have very low tensile strength unless and until reinforced concrete is used. For this reason the masonry contractors in MD suggest that thick walls should be made. Otherwise walls should be made by making vertical columns at intervals or else wind posts can also be added. The wall which consists of clay made bricks, these bricks being installed on one or both sides of the independent wall either made of wood or masonry is known to be as a masonry veneer wall. For decorative purpose brick masonry is used at masonry contractors in Washington DC. Here brick tiles (metal strips) are used to connect brick veneer to the structural wall. An air gap between brick veneer and structural wall is also to be provided.
The surface of the structural wall is to be waterproofed by using tar paper and weep holes to drain moisture through the air gap as the clay based bricks are not water resistant. Concrete masonry units or better known as CMU are cinder concrete, ordinary concrete and hollow tiles. Their size is very large as compared to ordinary bricks and so a wall is easily made up with CMU rather than by bricks. The moisture absorbing capacity of CMU is very low as compared to that of bricks. In veneered brick masonry CMU is used as a structural core to form a concrete stone work in MD. The prime advantage is CMU over bricks is that it can be easily reinforced by filling voids with concrete with or without steel.
