What is the cement/sand ratio for brickwork. I will be building a BBQ in the
near future.
Is it necessary to add lime to the mortar mix? If lime is required, can I
use a plasticiser instead? If I can use, where can I buy plasticiser?
TIA



Anything from 2:1 sand:cement to 5:1 or even 7:1 will hold bricks together.

Opinions are divided between the '2:1 will be imprevious, and therefore
won't suffer water penetration and frost cracking' (but the bricks may)
to 'i'll use something with lime that is so soft that it won't crack
even if water does get in'


I ended up with a sort of 6:2:1 mix of sand:white portland:hydrated lime
for a visually pleasant mortar. One time I ran out of cement almost and
it ended up 8:1:2 and it set all right ;-)
