2. Learning Outcomes After learning this section, you will be able to • know some professional words and expressions; • know basic information about bricks; • know different bonds of bricks; • know specifications of brick construction;

3. length Information of Brick width height

4. length ＝ 240mm width ＝ 115mm ＝ 53mm width height Coordinating principle: the length ＝ the width of two bricks + a mortar joint height

5. Information of Bricks broad face 大面 long narrow side 条面 short end 顶面

10. Mortar • Gelling agent (cement, lime)胶凝材料 • Fine aggregate (sand, stone powder)细骨料 • Water水 • Additive外加剂

11. thickness: half- brick thick Thin, poor in bearing loads, poorer sound reduction stretcher bond 顺砖砌合法 orientation of the bricks: stretchers

12. English bond一顺一丁砌合法 Thick, one of the strongest bonds, good at bearing loads, good sound reduction orientation of the bricks: one course of stretchers and one course of headers thickness: one-brick thick

13. orientation of the bricks: two stretchers and one header in one same course thickness: one-brick thick Thick, not as strong as English bonds, more beautiful, Flemish bond（梅花丁砌合法）

14. How to choose the way of bonds? • Cost • Load-bearing ability • Damp-proofing • Aesthetics
