Status Update: Burning the Ash- 6.5 kg
Hello reader!
I just met with Nick today (online). He said that despite the burning for a while at hot temperatures, the Coconut Shell Ash still contained a good proportion of carbon (seen in the black powder below). Also note that the containers have seen better days, as the comparison between the images below shows.
Currently, around 6.5 kg of fully burned CSA has been produced, which is fairly far from the 20-25 kg of material used last time. What this means is that we either:
Push the concrete-making day at Cemex back from 3/21 (although I'll be in Japan from the 29th to April 8th)...
And/or reduce the amount of burnt CSA needed at for the testing. This could be done by getting rid of the shrinkage mold testing (leaving only cylinder molds for compressive strength testing) and by reducing the replacement percentages of cement with CSA (previously 15, 25 and 35%)
This testing is an important part of my project, so it's essential to balance getting it right/up-to-standard and getting it done in time. Hopefully the steel containers hold up, and I'll update again soon.
Thanks for reading
Max Polosky
