List of parts belonging to the semi-circular arch test bench
Storage plaque :360 x 185 x 10 made of expanded PVC includes:
- 7 polyethylene voussoir pieces (brick colour)
- 10 spandrel pieces (brick colour)
- A template: 180 x 115 x 10 made of expanded PVC.
- 1 base: 480 x 80 x 6 made of expanded PVC
- A bag of 36 blocks: 45 x 30 x 20 made of white polyethylene
The storage plate makes it easy to see if the test bench has been completed.
The base with a grooved foundation allows the blocks in the front row to be alig.ned and secured.
The template allows the arch to be assembled easily.
The 17 parts of the arch, as well as the 36 blocks are made of polyethylene:
It is light, rigid and pleasant to touch because the edges aren’t sharp.
It is used mainly for making cooking accessories such as worktops and chopping boards.

It is light, rigid and pleasant to touch because the edges aren’t sharp. It is used mainly for making cooking accessories
such as worktops and chopping boards. The blocks are polyethylene and are used to stabilise the
low profile arch by constructing a wall on either side. They can also be used to investigate methods
of constructing a stable wall.
