How many bags of concrete are in a cubic yard?

A:

Quick Answer

There are 45 80-pound bags and about 60 60-pound bags of concrete in a cubic yard. Each 80-pound bag of concrete covers about 0.6 cubic feet. There are 27 cubic feet in a cubic yard: 27/.6 = 45.

Full Answer

Though the number of 80 pound bags is exact at 45, overestimating the number of bags needed is a common construction practice to account for the minor variations found in building materials. In addition, most building applications do not use perfectly cubed yardage of concrete, as most slabs are poured just four to six inches thick, and footers for deck support tend to be cylindrical.

    How do you pour exposed aggregate concrete?

    A:

    There are two primary steps to pouring exposed aggregate concrete, according to the Concrete Network. The base concrete is mixed and then poured into slab form using a shovel or concrete mixer, where it is struck off and bull floated. The decorative aggregate is then spread over the slab by hand or shovel until it covers the top of the slab and the embedded top using the bull float.
