@@KurtisHord uhm no problem man, it's just a comment thread on youtube, no need to be so dramatic. Just to clarify, I wasn't saying this method was lost knowledge. It was learning exactly out how the romans used the lime in a hotmix to create their concrete that wasn't known. Long before the middle ages. They recently discovered how they mixed the type of concrete they used and it is very similar to how traditional mortars were mixed for hundreds of years until the 20th century.
Portland limestone. They called it Portland cement because it weathered to a similar colour and as advertising, since Portland stone of very high quality and status
US Heritage in Chicago sells conservation-grade lime products. I wonder why the need to mix quick lime directly though. Usually, slaking the quicklime a few months before use is preferable.
@@ArtEssentialsNigel Copsey (the guy in the video) has demonstrated elsewhere that using quicklime, hot mixed as here, is more historically authentic and has technical advantages over putty mortars in most situations.
maybe some humidity got to it and it was hard chunks. What sucks are YT channels that the creators dont come and answer any questions with those interested. I wanted to know about Dolomite lime, and it harder to find.
Turns out, this is pretty much how the Romans mixed their concrete and it has lasted thousands of years.
@@causalitymastered War is bad enough right now I'd hope it stays a secret to be honest!
@@KurtisHord Literally discovered at the beginning of the year. Didn't claim to be a builder. This was lost knowledge.
@@KurtisHord lol are you ok man?

@@KurtisHord badass much respect
How would you do big quantities?
Hi..what ratio is the mix.. looks good
Looks to be 1 to 1
Nigel why does it say Portland hotmix? I thought Portland was totally different than high calcium quicklime?
He’s talking about the place Portland I believe

Is this for 1929 buildings that had some cement in them?
More similar to Roman concrete
In America 🇺🇸 where can this type of lime be purchased? Can quickrete and this lime be used? This is very interesting.
It's just quicklime or unslaked lime. You can likely get it from the companies that dig the limestone.
@@terrijuanette486 How do you find these companies that "dig" limestone?
@@VenturaITmintek, or Mississippi lime. Or from me I got 2 tons in Indiana currently

hi why does the quicklime come in the big rocks?, does it also come in powder, also is it cheaper to buy the big rocks if it comes in both?, thanks
You can buy it like this, as kibble or as powder.

@@philindeblanc It's actually normal for home made quicklime to be in rock form
Have you got a mask on?
Does ur assistant!!
Asia , use sticky rice and anti bacteria powder to make hard concrete
