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 👍

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.

Hey rob curious how the mortar set up after being brought back to life thanks !

@papalegba6759 3 жыл бұрын

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.

When you say Lime, what lime did you use?, theres many diffrent varations and strengths,

@robsonger1 2 жыл бұрын

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

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?

@robsonger1 3 жыл бұрын

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

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

@robsonger1 3 жыл бұрын

yes, its about a 7-8mm joint depending on how the bricks come, occasionally it might even go down to 6mm, I love it..

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.

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.
