Another weekend, another day of concreting. Once done, there are 3 patios to fit, another observatory, rolloff, a Summerhouse and a workshop! That’s a lot of concrete and cement mixing!!! So you guessed it, more ballast!
Similar time as before 8:41 am and Luke and I removed the carpet from the old concreting which separated the block from the observatory base. This was carpet and plastic. We worked out that removing it was hard so the next time we would remove after 4-8 hours, time for the concrete to set and not slump but not so hard you have to use a cold chisel and lump hammer to remove.
Given the depth of the South side of the observatory base, we decided to place a lot of flint material on the base, this again would reduce the need for so much concrete. Another slump test and another successful mix.
By 10:40, some 2 hours later we were done. The join was a bit rough but we could chisel that down later if needed.
The spare cement was used to concrete in a manhole cover that was not concerted in by my house, also I used some to start the base of the small brick pillar nicknames Fraggle Rock by Gingergeek and 2 bricks for the electric to be fixed onto later.
Just before evening set in I went to inspect the concrete and cover before it got cold, I noticed a bird had clearly walked across it, that will now be some heavy bird I guess 🙂
