Reet, you made me watch it. Enjoyable enough quick film for a midweek nighthave you seen the movie? If not please do.
But.... The volume of concrete they were all getting excited about was about 150m3, taken more home in my turn ups. We do 1000m3 every day in the north east. My record is 10,500,m3 in a single pour.
The strength had to be C6... just about the weakest concrete available, should be a C50 or 60 for a tower, I'm not going in his building !
No idea why they didn't actually speak to a builder at any point
