Sand and gravel together
What I usually use is: 1 Part Portland Cement 2 Parts Medium to Coarse Sand 3 Parts Gravel or Rock
If you wish to get cement it's better to buy it bagged. If you wish to make concrete using the ratio suggested there would be 64 sand to 80 of gravel.
The typical ratio of cement, sand, and gravel in concrete hollow blocks is often around 1:2:3, meaning one part cement, two parts sand, and three parts gravel. However, this can vary depending on specific requirements and block designs, with some mixes using a ratio of 1:1.5:3.5 or similar variations to achieve desired strength and workability. It's essential to adjust these ratios based on local materials and structural needs.

The mix ratio of type 2 concrete is one part cement, two parts sand, and three parts pea gravel. You can also use sand or crushed stones in place of the pea gravel.

The recommended mix ratio for Portland cement in concrete is 1 part cement, 2 parts sand, and 3 parts gravel or crushed stone. This ratio helps to achieve optimal strength and durability in the concrete.

The type of sand is also important. The right ratio for a mixture of cement and sand is 1:5 to 1:6
The typical mix for concrete often uses a ratio of 1 part cement to 3 parts sand and gravel. Therefore, for every sack of cement, you would typically use about 3 sacks of sand and gravel combined. However, the exact amount can vary based on the specific mix design and the desired strength of the concrete. Always refer to specific guidelines for your project for the best results.
