Day 8 - concrete blocks

We removed the formwork for the concrete and prepared the site for delivery of the concrete block for the walls.


The concrete blocks were placed on the slab with amazing grace and precision.

The hollow concrete blocks are 21.5cm wide. We could have used a narrower block to satisfy the structural demands of the wall, but it would have been trickier co construct as most of the blocks need to be threaded down over the vertical rebar.

Most of the blocks for the walls fit into the slab, and if we are careful not to break any, we will have enough for the perimeter posts (we only have a buffer of about 6 surplus blocks out of the total delivery of 720!)

In total there is about 9.2 cubic meters of concrete in these blocks.
