SweetPDZ Zeolite geopolymer first try... Promising

[coastalrocketeer]

5 samples curing in the oven at 170F/77C

  Some are gaining strength faster than others, but all have gained more strength than the minimal amount of water that has escaped with the lids on would dictate, so some polymerization is presumably happening.

 A couple will be hard enough to de-mold and start faster drying tomorrow, others will need more time to gain that level of strength, up to days or weeks.

Have you new results this year?
I'm currently experimenting with zeolite and fireclay,and I'm getting flash setting and very lumpy results.

Flash setting can only happen if one uses a lot of cement respectively quicklime or adds it to early.

With lumpy results it is likely both, to much and to early.

Any kind of accelerator should be added at the very end of the mixing.

What kind of fire-clay are you using, what other ingredients, and what ratio of ingredients, including H2O?
