The formula for concrete calculations is (length x width x depth) divided by 27. The result of this formula provides the number of cubic yards of concrete needed. The measurements must be in feet in order for the equation to work.Know More
Concrete is comprised of several components including water, Portland cement and aggregate, which is granular material such as sand and rocks. Portland cement commonly comes in a powdered form and is the binding agent in the mixture. Proper hardening of a mixture requires a humid environment to achieve optimal strength. In environments where it is difficult to ensure constant humidity, such as the outdoors, water is sprayed on the concrete, which is covered with a plastic sheet. The aggregate materials provide reinforcement and determine the density of the finished product.
There are a variety of concrete densities. Concrete for standard use is premixed with inexpensive lightweight aggregate such as gravel. High-density concrete require heavyweight aggregates such as barites, magnetite, iron or lead. The use of high-density concrete occurs in the construction of nuclear facilities and places where it is necessary to have high structural integrity while taking up little space. It is more costly than standard concrete, but provides superior shielding against radiation while being more cost effective than lead or steel alternatives.Learn more about Building Materials
Concrete slabs should be 4 inches thick for normal residential construction. A slab should be 5 to 6 inches thick if heavy vehicles, such as motor homes or garbage trucks, will be parked on the concrete slab.Full Answer >
A concrete floor should be about 4 inches thick if it is in a residential home or building. For a building supporting heavy loads, 5 to 6 inches is the recommended thickness. A good quality concrete floor will have even thickness throughout.Full Answer >
Reinforced concrete is a composite material that provides superior compressive and tensile strength, according to the Concrete Reinforcing Steel Institute. Commonly used in the construction of bridges and highways, reinforced concrete is one of the most economical and durable construction materials available.Full Answer >
