Using lime in mortar

[Launchbury]

Reading through this site I have found I need the following to lay 2000 bricks;

2T of building sand
16 bags of cement

However, if I wanted to use lime and have my mortar; 1:1:6 how much lime would I need to buy.

I understand lime comes in 25Kg bags, but they are twice the size.

Does it mean I will need 8 cement and 8 lime, or 8 cement and 4 lime?

Any help appreciated.

it`s done by volume ( you probably know that )so you have to judge the volume of the bag of lime . Gauge it all in a bucket/ container of a useful size - and remember cement packs down slightly in it`s bag . - Further than that I haven`t got a clue

Whilst I use lime in render base coat, I use a plasticiser (Febmix) in bricklaying mortar. I’m no brickie & don’t do a lot except on renovation works but I thought using a plasticiser removed the need for lime

Any commenst from the brickies

BS 5628-3 is supposed to give guidance on batch mixing or mortas, but so far I have been unable to find a free download link.

Does anyone have a link for BS 5628-3?

I've got BS 5628-3 it's a 136 page document that contains a plethora of information on mortar. There's a Table 13 - Masonry Mortars that lists different strength classes is that what you're after?

The lime does the job of the plasticiser although I have used lime mortar and put a "drop" of Feb in it. Have not seen Feb (plasticiser) available round these parts for about 5 years Rich, used to swear by it. Didn't think it was available anymore have to use Sika or BM own brand

One very good point, so take note.

NEVER EVER EVER drop a bag of lime in an enclosed space...................

I did, not pleasent, not by a long shot!

I won't know untill I am able read it.

My interest in the document is whether it has mortar mixes by weight as BS 5328 part 2 1997 has for concrete
