Half brick walling calculations

  1. 1. Half Brick WallingBasic Calculations Stonemasonry Department 2012
  2. 2. How Many Courses?Using the brickwork dimension 8table provided by your course 7tutor, you can identify howmany courses of brick 6are required to build a 5 600mm 525mmbrick wall of a 4 450mmspecific height. 375mm 3 300mm 2 225mm 150mm 75mm 1
  3. 3. Activity 1Without using the brickwork dimension table complete the table below No.of Courses Height (mm) 75 3 300 6 7 675 12
  4. 4. How Many Bricks Long?Similarly you can quickly identify how many bricks are required to build a wall of a specific length.215mm 440mm 665mm 890mm 1115mm 1340mm 1 2 3 4 5 6
  5. 5. Activity 2Without using the brickwork dimension table complete the table below No.of Bricks Length(mm) 1 3 900 6 7 2025 12
  6. 6. A Square Metre of Brickwork 1m 1m In every square metre of half brick walling there are 60 bricks. We can calculate this by working out the surface area of one brick (including mortar) and seeing how many times it fits into an area 1m long and 1m high.
  7. 7. How Many Bricks?Before a bricklayer starts a project they will calculate the number of bricksrequired to complete the project. They can then order the bricks knowing they will have enough materials (but not too much). To calculate the number of bricks required for a half brick wall youmultiply the surface area by 60 as there are 60 bricks per square metre.
  8. 8. Activity 3 3m 10mThe wall shown is 10m long and 3m high. How many bricks are required to build the wall? Number of Bricks = Surface Area x 60 Number of Bricks = (10 x 3) x 60 Number of Bricks = 1800
  9. 9. Activity 4 2.6m 8mThe wall shown is 8m long and 2.6m high. How many bricks are required to build the wall? Number of Bricks = Surface Area x 60 Number of Bricks = (8 x 2.6) x 60 Number of Bricks = 1248
  10. 10. Activity 5 1.5m 6mThe wall shown is 6m long and 1.5m high. How many bricks are required to build the wall? Number of Bricks = Surface Area x 60 Number of Bricks = (6 x 1.5) x 60 Number of Bricks = 540
