GFRC Mix and Materials - The Concrete Network

Sand and cement are typically used at a ratio of about 1 to 1, although some mix designs call for slightly higher cementitious materials content (see "GRFC Mix Design," Concrete Décor, June/July 2008). With its high cement content and low water-cement ratio (0.33 to 0.38), GFRC can dry out quickly and not gain full strength.

How to Properly Mix Concrete (DIY) | Family Handyman

Whether you hand mix concrete in a plastic tub, homemade mixing tub or wheelbarrow, the technique is the same to find the right concrete mix ratio. However, it's easier to move and dump concrete that's mixed in a wheelbarrow. For larger jobs, you could rent a mixer ($35 per day), but it may be more economical to simply order ready-mix concrete.
