The amount of sand and gravel you need for a bag of cement depends on the specific project and the mix ratio you’re using. A common mix ratio for concrete is 1:2:3, which means one part cement, two parts sand, and three parts gravel.
For one bag of cement, which is typically 94 pounds (about 42.6 kilograms), you would need:2 parts sand: 2 x 42.6 kg = 85.2 kg of sand. 3 parts gravel: 3 x 42.6 kg = 127.8 kg of gravel. So, for a 1:2:3 mix with one bag of cement (94lb, or 1 CF), you’d need approximately 85.2 kilograms (2 cubic feet) of sand and 127.8 kilograms (3 cubic feet) of gravel.
There is a good mix of cement, sand and gravel require during the preparation of concrete mix for achieving the targeted compressive strength of any structure like Foundation, footing, slab formation, for driveway, roadway and pavement, street.
