I googled Gen3 and got responses which stated that this is an obsolete code now replaced by C20. C20 mix is 1:2:4 but I suggest you google C20 for a fuller write-up. And this site gives you a rather nice calculation of material requirements http://www.bulkbagman.co.uk/calculator/c20_concrete_mix_estimator/index.html
