What "cement" mix should i use?

[myakpaul]

This is an amazing forum and i wish i had found it before i got as far as i have....anyway! I am about to build my oven which will sit ontop of a purpose built concrete base with a structure that includes a wood storage area. My question is what "cement" mix should i use for my storage heater blocks to create the oven?

Thanks alot in advance

The 'homebrew' mix in general use is a ratio of 3-1-1-1 Sand/cement/clay/lime, others have used 5 measures of sand but I used 3 and it's fine.

i used Wickes grey sand and cement, locally sourced lime and powdered clay from a potter's suppliers, although Jewsons apparently stock it all.

Are you using heater blocks for the dome or just the floor ? I used them for my floor, but used half-bricks for the dome. Got 10 spare heater blocks if you need more.

Thanks so much thats very usefull ans also for your kind offer. I was planning on using the heater blocks for the floor and the first section of the dome. I then have victorian clay reds that I will use for the remainder of the dome.
