Mix concrete by using 1 part cement to 2.5 parts sand. Add 0.5 part water and the appropriate amount of wet aggregate. The amount of aggregate will vary according to its size. See the table in the resources section which indies the amount of aggregate you will need to add to your concrete mixture.

Can portland cement be mixed without sand or gravel?

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. Only enough water should be added to afford workability and eliminate voids in the mix. The less water you use, the higher the
