Notes for data mentioned in the following tables:

  • The Practical daily productivity is with 7 people in the block yard: 3 people for mixing, 1 operator, 2 people on the lever and 1 man stacking for the initial curing.
  • The quantities of materials are calculated with 5 % cement for a soil/sand mix which has a ratio of 80 % soil and 20 % sand.
  • The bags of cement mentioned are 50 kg.
  • The quantities of blocks per bag mentioned hereafter are indicative and they will vary with the soil type and the compression ratio of the press.
