Hydrated Lime: Different sources/forms in N. America

I’m curious to see if we could get a list going of what types of hydrated lime folks are finding and using in different areas of N. America.  

I’m just starting to do some sampling, and was planning on Type S (Natural hydraulic being cost prohibitive esp with shipping) but I havent been able to find it locally.  

I just picked up a bag of “water treatment” high calcium lime from our feed store.  It is still calcium hydroxide, and with my very limited knowledge the main difference is that type s may have much higher levels of magnesium.  Can anyone speak to this being right, wrong, or otherwise? I’ll attach a photo

Context:
- I’m considering mixing a lime mortar for a very short stone veneer wall instead of the standard Portland cement.  
-I mixed up/slaked? Half of the bag with water to let sit and see what it does
-we are planning on doing some lime plastering this fall as well so this is also R&D for that.

If you have any insight on non “type s” or whether this Ag hydrated lime is the same feel free to chime in.  Also if you’ve used a specific form of hydrated lime and seen good or bad results I’d love to hear it!

 

I'm in the process of plastering my gate. I'm using Lhoist High Calcium Lime in 50 lbs bags. I purchased it locally in Fresno in a plastering supplies store. Around $20 per bag. It does not say "Type S".
I mix it with water in 5 Gal buckets using paddle on SDS drill to get warm cream cheese consistency. Then I cover the top of putty with 2 cm of water, cover the bucket and soak for 2-3 days.
I determined the volume of cavities in my sand using 70% alcohol and it turned out that for 200ml of dry sand I needed to use 90ml of alcohol to see it shining on top of the sand. So the ratio is 2.2 sand to 1 part of lime putty.
I take putty, mix with sand, add some water and mix with a hoe. Then I add rice straw (< 5cm long strands) in the amount of 1/3 volume of sand.
The gate is built from bricks, we wet it enough to make it moist, but not flowing with water. First coat was 6-7mm. The key is to keep it protected from direct sun, and keep it most for a few days. It already hardened. I still keep it shaded and spray daily.
We will continue with the second coat without straw. I could use one coat, because the walls are very straight, but wanted to do fiber first and no fiber in the second.

Just to follow up ended up using the Lhost hydrated lime for mortar on our stone wall a couple months ago and it’s set up great.  Did 1 lime to 2.5 “masons” sand and a sprinkle of wood ash.  It was extremely workable and set up within a few days with what seems like good hardness at this stage.
