1.	Why Shape and texture of aggregates is a must?(a) Smooth surfaces give better workability(b) Smooth surfaces give poor workability(c) Rough surfaces give better workability(d) Rough surfaces give poor workabilityThe question was asked in semester exam.I'd like to ask this question from Workability of Fresh Concrete topic in section Fresh Concrete of Concrete Technology
Answer» Correct choice is (a) Smooth surfaces give better workability For EXPLANATION I would say: The USE of smooth and rounded, rather than IRREGULARLY SHAPED aggregate also increases workability.
