driveway f62 steel ok?
Page 1 of 1
the concrete guy will be using f62 steel for our driveway and front- is this alright for a four door sedan to drive on. Also there is about 3 cracks in the concrete from the back yard which was done last month- can this be fixed? He said he will repair it. We used f52 steel for the back yard.
Your better off moving this topic to the concreting and paving section. You might get a better response.
How thick is the slab? How wide is the slab? How long is the slab?
mPa of concrete?
From https://forum.homeone.com.au/viewtopic.p ... 542#118542
mpa strength is dependant on the agg. mix you choose.
25 mpa is the starting point for trafficable conc.
32 mpa for stone below 7mm and or glass agg.
32-42 mpa for terrazzo weather grind and sand blast or polished
min. drive reo = rl62 for standard vehicles
rl72 for medium vehicles (4x4)
rl72 for light commercial as well
rl82 for heavy commercial
rl92 for light industrial
double rl92 heavy industrial
