M10 concrete for raising concrete slab prior to tiling - TilersForums.com

[kkckkc]

I am tiling the garage floor. Can I use M10 concrete to level and raise/level the base concrete slab before tiling? It would be cheaper as I have about 100kg of M10 left over from the house construction. Thanks, kkckkc.

M10 concrete?? What's that??

I think its probably some concrete left over from when they built the M10 in Hertfordshire. Probably gone off by now. :lol:

it's a standard notation. M10 is defined as ratio 1 : 3 : 6 (cement:sand:aggregate). Typical use is for foundations and mass concrete works. Here is a relative table: M10 1 : 3 : 6 foundations and mass concrete works M15 1 : 2 : 4 normal works M20 1 : 1.5 : 3 M25 1 : 1 : 2 very high strength

Never heard it like that but no a 1 :3 :6 is to suitable for a garage floor. Generally you would need a minimum 1 : 2: 4 for a covered garage floor so in your notation an m15.

1: 3 :6 will have approximately 170kg of cement per m3 and really you need a minimum of 270kg/m3. If you have a lot of m10 and can mix an extra 100kg per cubic meter into it thoroughly it would work.
