This is what confuses me, portland cement ingredients (if I am reading correctly) is like 60% lime, sand and other metal oxides, so isnt portland cement basically lime?
Hi Robert, You CAN add lime to Portland cement to make the mix more plastic, and increase the workability. If your plant pots are cracking I would guess you used a bit too much water in the mix or it dried too quickly. Next time, try a little less water and put a plastic sheeting around the pot as it’s curing to prevent the moisture from evaporating too quickly. Good luck!

Lime is the only option for soft stone or soft brick. Period.

Which is better to make compressed earth blocks, and why? Thank you!
Terrific video. VERY informative! How come neither Lowes or Home Depot sells lime?
Thanks for the question Dan. I was wondering the same thing!
I've seen lime in every home Depot
It's basic for stucco mix they all carry it in building materials next to Portland cement
So, are "Lime" and "Mortar" the same thing?
Recipe for lime mortar?
Thank you!
Can I ad lime for flexibility to Portland cement ? I'm making cement pot plants only small ones but I have noticed cracking
