Auram Blocks Data

The frame of the Auram press 3000 can presently fit 17 moulds to produce about 75 different Compressed Stabilised Earth Blocks.

These series are available Plain square blocks Plain rectangular blocks Round blocks Hollow square blocks Hollow rectangular blocks Hollow square interlocking blocks Hollow rectangular interlocking blocks Plain square interlocking blocks Plain rectangular interlocking blocks Various special blocks 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.
