what do you think they use in time critical airport pavement repair ? Overnight road repair ect ?

if you don’t think you can achieve 50mpa in hours ( ie under 24 hours ) then I don’t know what to tell you…. there is even retail available grout options that you probably use with panels. It’s called uhpc.

here is one you might understand, why do you think they cool down the batch water in fnq sometimes when it’s very hot ? Could it possibly be to slow down initial set & curing

70/30 rule is a guide for standard mixes not a rule

and after all that very poor and mostly wrong commentary you have missed the point… that faster curing times aren’t a sales point. You can today order nearly anything your heart desires even 22@1 day for your panel lifts. The vast majority of customers don’t because it’s not worth it economically when you have other pours to prop form and strip. Hence why a 3 day program is the norm.
