What nominal maximum sizes of aggregate are Concrete

What happened when we not used 20 mm size aggregate in

Your question is not clear. Do you want to use concrete with nominal maximum size of aggregate less than 20 mm (i.e. 10 mm, 12.5 mm or 6.3 mm) or you wish to have concrete with say NMSA 40 mm and jumping to 10 mm while grading.
