C20 concrete has a characteristic compressive strength of 20N/mm2 - what imperial strength concrete should we use?No takers then?
I'm not going to even try it in Imperial.
The same dimensions in metric are :- 10 m x 10 m x 0.1 m = 10 cu m. = 3.2 T cement, 6 T sand and 12 T aggregate = 21.3T
10 cwts is almost the same as 0.5 T so he will have to go 43 times to collect 21.3 T
The trailer is 2 m X 1.5 m x 0.5 m = 1.5 cu.m - so the volume of the trailer is not a limiting factor.
