Basically the program allows you to enter up to 8 coarse and 5 fine aggregates and uses MS Solver to determine the most economical combination of these.
Also includes air% in the variables covered and to eliminate the comparison of predicting 28d strength by adding average 7-28 gain and by assuming a % increase (because the former has been clearly and conclusive shown to give better results, so it is now the only method used)
