How to Make Lime Cement DIY with traditional principles

- We made a temporary lime kiln to burn some lime and make it into lime mortar as part of a lime mortar course for traditional Scottish stone restoration. This video shows the steps to build your own kiln using concrete blocks, 2 buckets of coal and a bucket of limestone.
The second video shows how we turned it into lime mortar and waterproof white wash!
This video was recorded while I was on "Introduction to Masonry Repairs in Traditional Buildings (P1)" by the Scottish Lime Centre.
This is part 2 of the Kiln
• Lime Kiln 2
Then we looked at making lime mortar
• Lime Mortar Experiment...
You can also use it to make waterproof whitewash. It’s excellent for protecting external walls and buildings.

These techniques could be very useful for developing countries where cement is very expensive compared to labour costs. The solution is to take a night to build a kiln and make your own lime cement. We have been doing this in Scotland for hundreds of years. It’s what’s protected our buildings from the weather.
Every farm had their own little kiln so they could make their own lime cement, mortar and paint within 24 hours.
I did this all as a traditional lime work course at the Scottish Lime Centre.

This was very helpful
How do you make the actual cement?
Add water and sand.
This was very interesting, thanks for posting this.
What is this place where they're working ?
heaven
Good informational video
Wonder if you can use something other than coal?
Coal is pretty cheap and easily available in the UK
Charcoal was traditionally used. Limekilns are often found in woodlands, where there was a ready supply.
@@francisclark9059 no it wasn't as it doesn't burn hot enough and is doing something twice whilst wasting energy for no reason. They used timber or coal traditionally.
I was sad when it ended in the middle of a sentence and there was no part 2
How many blocks did you wind up using?
"Ideally, the height of the kiln should be 5-6x it's diameter" -HNIC
Assuming those are 16" long by 8" wide by 4" deep blocks, the inner "diameter" side to side is 8", the diagonal is 11.31" the average is 9.66"
(9.66)5.5=53.1"
Which it clearly isn't, as that would be 4.5' plus the 8" on the bottom, and all of these guys are surely taller than 5'3"
Assuming he meant OD (outer diameter), which doesn't make much sense as a useful engineering measurement, it would be about 12' tall minimum.
It looks to be 7-8 feet tall, you need three courses of 4" block (it's really 3.625" but let's not get TOO technical as drunky Magee pulled it off fine anyway) to get a foot, and four blocks to get a course, so you need twelve blocks per foot.
12(8)= 96 blocks
12(5.5)=66 blocks
12(12)=144 blocks
Can You use 2 year old lime to make whitewash? I've heard that lime that is more than a year old can't be used for certain applications.
It's like eating leftovers. The longer you wait, the less effective it will be.
@@skeetorkiftwon As long as the slaked lime is kept underwater it will last indefinitely. In fact some people that do plastering think that it gets better with age.
Slaked lime becomes hard again by absorbing CO2 from the air.
Absolute boy!
Hmm, now volcanic ash is rock which has been super heated by the core of the earth... which was used to make the first concrete. Heated like this coal heated it.
I wonder if those underground fires in abandoned coal mines, ones which burn for decades, they might have the same effect.
Its called pozzolana. Coal ash is mild at best as it only burns low in comparison to volcanic material such as trass or tuff. But yes you're right.
With the shit is this? It cut off before we ever saw the results of the work? Who upload to video like this without showing the results?because this was incredibly interesting video and I want to see the results LOL why would you do that? Put a part 2 up!
