Concrete trucks come in different sizes, but the typical truck can hold between 9 and 11 cubic yards of concrete. Premixed concrete is sold by cubic yards.Continue Reading
Concrete is used at least partially in most structures made in the United States, from bridges to houses to dams. It is composed of a mixture of sand and rock and a paste consisting of cement and water.
The strength and durability of concrete is achieved by reaching the correct proportions of the ingredients. There should be 10 to 15 percent cement, 60 to 75 percent aggregates and 15 to 20 percent water. Air bubbles can make up to 8 percent of the composition.Learn more about Building Materials
Precast concrete is concrete that's been poured, dried and treated away from the work site and transported into place. Precast concrete is a popular construction material for office buildings and other large structures.Full Answer >
To mix concrete by hand, pour half of the ballast on the working surface, and make a crater in the middle. Pour cement into the crater, pour the remaining ballast over the cement, and mix with a shovel. Add water, and mix until the mixture is smooth and plastic.Full Answer >
The density of normal concrete is about 145 pounds per cubic foot. The density of concrete is determined largely by the type of aggregate used in the mixture. The density of the cement used in the mix can also affect density, with compressed, vibrated cement creating a denser concrete mix.Full Answer >
Concrete is thinner, stronger and more durable than mortar; whereas mortar is used as a bonding agent between building materials, concrete is used for structural projects, such as beams or walls. The differing compositions of these materials makes them ideal for different purposes. Concrete and mortar are not used interchangeably without compromising the structural integrity of a building.Full Answer >
