Can portland cement be mixed without sand or gravel ...

Without aggregate, you're basically going to have grey plaster with little inherent strength for both tension and compression. Even small aggregate, sand and pea gravel, will make a significant difference in the strength. Aggregate to cement proportions should be about 3 parts aggregate to 1 part cement by volume for field/hand mixed concrete.

Aggregate Sizing Explained - Chaney Enterprises

Jan 15, 2016  Aggregate serves as a reinforcement to add strength to composite materials such as concrete. Aggregates can be categorized into three groups: fine aggregate, coarse aggregate, or all-in aggregate. Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 4.75 mm IS sieve.
