How many bags of portland cement is needed to mix 1 cubic yard?

To mix 1 cubic yard of concrete, you typically need about 5 to 6 bags of Portland cement, depending on the specific mix design and the desired strength of the concrete. A standard 94-pound bag of Portland cement yields roughly 0.5 cubic feet when mixed. Therefore, for 1 cubic yard (27 cubic feet), approximately 5.7 bags would be required. Always check the specific mix requirements for your project, as variations can occur.
