How much cement is added to a 300mm brick wall?
To keep emissions to an absolute minimum, the consumption of fossil fuel and other combustion processes have to be avoided. If, say, 5% cement is added to a 300mm mud brick wall, it makes a fairly high energy/high emission building material, close to the embodied energy of a 125mm unreinforced concrete wall.
What is the ideal building material?
The ideal building material would be ‘borrowed’ from the environment and replaced after use. There would be little or no processing of the raw material and all the energy inputs would be directly, or indirectly, from the sun. This ideal material would also be cheap and would perform well thermally and acoustically.
Why is Portland cement used in bricks?
Because traditional Portland cement has extremely high embodied energy, its use in earth brick construction changes it from a low embodied energy material, to a moderate or high embodied energy material. Using cement erodes some of the greenhouse gas emission savings delivered by pure earth building.

Fire and Pest Resistance
- Since earth does not burn, and earth walls do not readily provide habitat for pests, mud brick walls have excellent fire and pest resistance. Note that a bushfire attack level (BAL) rating may still be required if located in a bushfire-prone area. Your local council can assist with this. Consideration may also need to be given for termite control i...
