- Ratio Of Crushed Stone
The basic ratios of sand, cement, and crushed stone must be understood in order to determine how much crushed stone is required in one cubic meter of concrete. A typical mix might consist of one part cement, two parts sand, and four parts crushed stone, or a 1:2:4 ratio. The concrete's strength and stability are guaranteed by this balance.

What Is Crushed Stone? Crushed stone is a man-made construction aggregate typically produced in a quarry by passing stones through a crushing machine. It is generally used as a base or underlayment, for example, where the concrete of a patio will rest. It's also used for drainage and landscaping. It is offered in a variety of sizes and stones.
