Concrete is composed of aggregates, which can be any or a combination of sand, gravel or rocks that is held together by cement. The cement itself, when mixed with water, serves as a paste that holds all the components of the concrete together once the cement sets and hardens.
To estimate concrete costs, acquire the contact information for three concrete suppliers, get quotes from each company, compare the quotes, and choose a supplier. The process will take approximately 24 hours and requires access to a telephone.
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.
The price for ready-mix concrete, on average as of 2015, is $93 per cubic yard. However, there are many factors that contribute to the final price, such as grading, subbase preparation, concrete forms and reinforcement.
Types of concrete include normal concrete, high-strength concrete, high-performance concrete, air-entrained concrete, lightweight concrete and pervious concrete. Each type is distinguished by strength level, weight and other unique features.
To pour a 4-inch slab that measures 1 square yard, use six 80-pound bags of concrete, and for a 6-inch slab, use eight 80-pound bags of concrete. One 80-pound bag of concrete covers 4 square feet at a thickness of 2 inches.
Concrete thickness and volume can affect the cost of removal. Steel reinforced concrete is harder to remove and thus takes additional time, so it is more expensive to dispose of. Some areas require a paid permit for any demolition project. The square footage of concrete to be removed determines some
"What's in your bag?" is a popular topic used by fashion, lifestyle and travel blogs. It asks participants to empty out and show the content of their bags.
An 80-pound bag of concrete yields 0.60 cubic feet of wet concrete when mixed with the proper amount of water. Concrete consists of portland cement, sand, stone, gravel and additives that make the substance cure when it dries. An 80-pound bag needs about 6 pints of water to mix properly.
It requires two 80-pound bags of standard concrete mix for a 4- to 6-inch-thick concrete slab that is 2.0801 square feet, which is equal to 3 cubic feet. So, two 90-pound bags of concrete should get the job done.
