Removing the formwork from our rammed earth wall. We embedded steel reinforcement and a cavity to experiment how the earth wall would cope with these insertions.
Mud bricks after one day of air drying. The bricks had become stuck to the formwork. This was because the mixture was very sticky, and also because the formwork was very rough and the mixture clung to the grain. The bricks were still slightly wet, and some of the bricks began to sag after the formwork had been removed.
Formwork and 'Frog' for my final brick prototypes.
Formwork and 'Frog' for my final brick prototypes.
I produced two bricks for my final prototype. The first brick wasn't a success. This is because I removed the formwork as soon as I had pressed the mixture into the mould with the frog. Even though the new formwork was very smooth and slid out fairly easily, the brick sagged instantly.
The second brick turned out brilliantly. I left this is the formwork overnight to ensure that it set properly.
