This chapter discusses brickwork materials and construction techniques. Bricks are one of the oldest man-made building materials, dating back over 4000 years. Bricks are typically made from clay but can also contain sand, lime, or cement. Common types of bricks include clay bricks, fly ash bricks and kiln-burnt bricks. Mortar is used to join bricks and consists of cement, sand and water. There are various bonding patterns used in brickwork such as stretcher bond, header bond and Flemish bond. Equipment used includes trowels, jointers, spirit levels and bricklayers' tools. Proper construction techniques such as joint spacing, bonding and laying patterns are important for quality and durable brickwork.
