5.10 Clay briCk
Clay brickwork is made from selected clays that are moulded or cut into shape and fired in ovens. the firing process transforms the clay into a building component with high compressive strength and excellent weathering qualities, attributes that have been exploited for millennia to build structures ranging from single-storey huts to enormous viaducts. Clay brickwork is australia’s most widely used external cladding and loadbearing wall medium. Clay bricks are readily available, massproduced, thoroughly tested modular building components. Their most desirable acoustic and thermal properties derive from their relatively high mass. Clay bricks are generally affordable, require little or no maintenance and possess high durability and load bearing capacity. The use of clay brickwork is informed by extensive Australian research, manufacturing and construction experience.
PerFOrmaNCe summarY appearance
Clay brickwork is available in a wide variety of natural colours and textures derived from fired clay used in combination with cement mortar joints of various colours and finishes. Bricks remain stable and colour-fast and do not need to be rendered or painted. Clay brickwork is most commonly used uncoated to display the richness and texture of the material.
4455 Masonry units and segmental pavers and AS 3700 provides the means of determining the strength of clay brickwork walls when subjected to horizontal loads resulting from wind, earthquake or fire. [See: 5.5 Construction Systems]
Clay brickwork has high thermal mass. If a building with internal clay brickwork walls and concrete floors is subjected to a heating and cooling cycle that crosses the comfort zone, the brickwork and concrete will maintain a relatively stable level of heat energy for an extended period. In summer, they will remain relatively cool and in winter, the same building will remain relatively warm. [See: 4.9 Thermal Mass]...
