Can you mix sand and cement to make concrete?

How do you mix C20 sand & gravel?

C20 is a general purpose concrete grade of 20 N/mm^2 or 20 MPa. strength. To make it you mix by volume 1 part cement, 2 parts sharp sand to 4 parts of aggregate, say 20 mm gravel for coarse concrete, or 10mm gravel for fine concrete. First confusion comes when all-in ballast is substituted for the separate sand/aggregate ingredients.

Does fine sand need more cement?

Very fine sand will require more cement in the mix, as the tiny particles have more surface area for the given volume, so more cement is needed to coat the sand for good adhesion. But fine sand is easier to mix, easier to work, easier to stuff into a place. If the surface it must attach too is very irregular, it may stick better.
