Recommended Mix Specifications for "Curb Mix" (Note: this mix does not have the 28 day strength of a true concrete mix.) Ingredients: • Coarse sand • Portland type I cement • Fiber • Water A batch of curb mix made in a 6 cu ft mortar mixer will produce 15' 20' of curb, depending on the cross sectional area of the curb being laid.
Concrete is basically a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and Portland cement. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete. Cement comprises from 10 to 15 percent of the concrete mix, by volume.
Jul 14, 2006· Best Answer: A properly designed concrete mixture will possess the desired workability for the fresh concrete and the required durability and strength for the hardened concrete. Typically, a mix is about 10 to 15 percent cement, 60 to 75 percent aggregate and 15 to 20 percent water.
The cement binds the aggregate, and the aggregate provides structure and reinforcement to the concrete, which helps to prevent cracking. The ratio for dry concrete mix is typically 4 parts aggregate, 2 parts sand, and 1 part cement.
