the fine art of brickwork - 200 year old mortar (Part 2) mixed up

- After salvaging this mortar from a 200yr old building, it was crushed up in the mixer, and now it's the time to find out how it mixes up again and is it really possible to reuse it after such a long time?
Lets find out.
Lovely bit of gear, we used to salvage the old morter some years ago when I worked on an old county estate ,if it was a bit dead we would add a trowel full of lime putty which did the trick as plastisizer was a no no as a lot of it was heritage work. If I need just one gauge I split it into two Gorrila tubs and use a plasterers forced action whisk can't be arsed getting the mixer dirty. Jobs looking good 👍
I have added putty for inside work or NHL 3,5 for outside and whisked in tubs.............lovely fluffy pug with a good set. Best wishes.
Rob...you should have a TV program! Traveling the world leaning and showing you're skills... I'd love to see you building in galway or Claire building tradition old wall's on the wild Atlantic Way
if you know a film producer, I'm up for it...
I’m looking forward to the follow up Rob the mortar mixed up great 👏🏻 nice
Grand master rob .so envious of your knowledge. You are the fred dibnah off bricklaying.
Lovely bit of gear mixed.
Brilliant corner, boss design .
I'd like to see a garden wall with them specials and a few pillars too.
Looks ( can't believe I'm saying this ) regal and majestic.
Hello Marcus, I'm cutting all those bricks with my DeWalt...awesome little machine
Loving your new vids rob, very interesting as always. All the best for 2021 🙏
Good job👍
What a bloody craftsman your are rob . Sadly there’s not many about these days
STEVE! ALEX! I think I accidentally removed your comment as I was replying!!
The gobbo almost as old as you haha
Now that’s time travel
To think 200 years ago someone used that same mortar
Always thought you could do this as it’s basically lime in the mix
Really good video.
Tapper Tone the lead worker used his Averling & Porter with great effect to crush a good old load down.
Any way brilliant subject with a great deal of myth and legend surrounding this excellent material
I find many Tradesman reluctant to study the facts about lime (a shame as a great deal is forgotten )
However men like your good self are shinning a nice light on things.
I should imagine the outer mortar has carbonated although
it has been established through research that some old thick walls on churches etc still have
active lime within them.
I have a mix that uses approx 10% crushed yellow stock that turns lime putty into a reasonable Hydraulic lime.
All the best to you interested commentors.
Thank you Rob.
It is said that yellow stocks only fire to a certain temperature, perhaps this is why it works well for me.
thank you Darrin, that was very interesting. Please keep watching for lots more content coming shortly.
Looks a lovely mix that, Rob! Only time I have ever used a lime mix was in college and it was never as good as that.
It turned out really well 👌👍💪
Hi Rob why are you wearing what appears to be a stab vest? Great video 🤣🤣🤣👍👍
My curiosity is exploding to know if it sets!
what'd give me pause about this mortar is that when you were grinding it up with the shot putts you may also have been grinding the sand finer & more uniform. which'd make it weaker & less weather-resistant than the original.
Very nice! Great idea for a video, many of us find this interesting. Please do a follow up👍
Very very very cool
When you say Lime, what lime did you use?, theres many diffrent varations and strengths,
It's the existing lime from the demolition. c1860, hydraulic lime, but its already carbonated so it is only really as strong as hydrated lime now, ideal for my workshop.
@@robsonger1 i see what your saying, i would reccomend a mortar anaylisis and at the very least an acid digestion, then we can really see what they where working with. Would be very improtant to get a perfect match on the rebuild. Good luck mate
Im no chemist but Surely that won’t set again by carbonation?
Yes thats my thought, but the wall is 450mm wide and a couple of people have told me the inner lime could still be live. My thoughts always have been to add fresh lime to it to give some strength back, but at the moment I'm still monitoring it and at the very least, its the best training mortar I've ever used.
Thats good Pug
Great looking tight joints, not like most the fat joints I see on you tube !
So cool 😎
Hey rob curious how the mortar set up after being brought back to life thanks !
looks good mortar out of mixer but be nice to see if it hardens,them brick quions look the business rob,i know they are imperial brick but was wondering what is the depth of mortar bed as looks quite fine on camera
yes, its about a 7-8mm joint depending on how the bricks come, occasionally it might even go down to 6mm, I love it..
what would they have used to mix this mortar originally rob? 🤔 and what kind of rashio roughly?
Used to see builders when I was a kid in the 1950's who had red marks on their cheeks, arms and hands . They used to say it was from the lime, must be nasty stuff but suspect not a large amount used today on commercial buildings.
it does burn, and the dust isn't good, but then no dust is good.. I try to use a mask every time I need it
@@robsonger1 Thanks for your reply. All the best for the coming year, you are a brilliant craftsman.
Get yourself a heated body warmer by deerhunter 😉 any gun shop near you may help or online
How do you mix that? Lime and what else? Regards mate
This will be interesting to see how the mortar works out, in the past we have used the old added to the new but never by itself
yes, my initial thought would be to do the same
Hello Rob, love your work & enthusiasm, looking for some advice! My young lad wants to learn the fine art of brickwork. We have acquired an old roller pan mixer as used in a collage for training purposes but are unsure of what mix is required! Would like your advice as to what mix you use?
1:3 (hydrated lime, sand) depending on the quality of the sand, you might need to go to 1:2, with a small amount of plasticiser
@@robsonger1 thanks for your reply Rob, will give 3 to 1 mix a go. Thanks for your input.
Your a gd trowel fair play
Why don't you use hot mix? That is what was used 200 years ago as you know.
Ur answer can be found a few vids back 👍
Nice experiment sir
Seeing is believing,you would have thought it properties would have broken down🤔
What’s with the buoyancy aid
HELLO ROB , CAN YOU TUCK POINT ,”. My old Tuck trowels are WORN OUT. &. The Only place to BUY THEM IS. AUSTRALIA.!!
God bless Jim
Yes, mine are from Australia
I need a lot more practice on tuck pointing
Must have been bloody hard work mixing lime 200 years ago, if a mixer does the job in 10 minutes!
