You cannot make concrete with only sand and cement because it requires a coarse aggregate like gravel. The stone component is the most critical, as that is what gives it its durability and strength. When mixing merely sand, cement, and water, you get a material closer to mortar.

What kind of concrete is used for footings?

A concrete mix of 1 part cement : 2 parts sand : 4 parts coarse aggregate (by volume) should be used for footings. Concrete must be placed within half an hour of mixing. Brickwork – Place your concrete into your trench. Work the concrete into awkward places and corners using a shovel.

What is the strongest concrete mix ratio?
