I am getting confused reading around the net about mix quantity.
I am looking to mix some concrete to make a hard standing area for a Pizza oven & total weights would be approx 400kg. Area is 1m square. I had to dig down 30cm due to the amount of bedding under the paving slabs I removed.
I have a jumbo bag of ballast which is a lot more than I need, but worked out cheaper than buying 1/2 the amount bagged.
I am not sure what mix to use. I guess I want something C25 (ready mix not an option since the distance from the road is to far!)
Can anyone give me some advice? I am reading 1:3 for C25 to 1:8 from various sites!
