What is the cement/sand ratio for brickwork. I will be building a BBQ in the

For that job, anything from 1:3 to 1:6 by volume.

Is it necessary to add lime to the mortar mix?

no

If lime is required, can I
use a plasticiser instead?

if you want

If I can use, where can I buy plasticiser?

Tesco, Sainsburys, etc. The rock bottom price washing up liquid at 15p

If you use lime to plasticise instead, use the same volume of lime as
