1. Explain the effect of S.S.A of all-in aggregates and NMS of aggregates on the conpressive strength of concrete.

2. At a given water-cement ratio, either a change in the cement content or aggregate grading can be made to increase the consistency of a concrete mixture. Which one of the two options would you recommend ? Why is it not desirable to produce concrete mixture of a higher consitency than neccessary ?
