What grade of concrete?

Anonymous user 01/03/2024 - 2.58 PM

I'll be having a 70mm thick 5.5m by 4.5m log cabin being made into a home gym. All of the weight of the building will be on the perimeter of the concrete slab. It will then have a suspended floor installed and then horse stall mats on top of heavy duty floorboards. What grade of concrete and how thick would you go for a building where all the weight is on the perimeter and then the centre will be having say 200kg deadlifts dropped on it, etc. I already have A142 6mm mesh for the job just need to specify how thick the slab and what grade of concrete I want. Thanks

I would suggest a 150mm thick slab with a C25 mix of concrete

In addition, if you can have RC concrete upstand all around the perimeter and the span across centre. That will further strengthen it. Hope this helps
