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.
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
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.Full Answer >
The weight of a sheet of drywall depends on the thickness, brand and type of drywall. A 4-inch by 8-inch sheet of 1/2-inch thick standard drywall weighs approximately 52 pounds. Moisture resistant drywall, or green board, weighs about the same as standard drywall.Full Answer >
Lowe's recommends giving special attention to ensuring the flexibility of the vinyl panels when installing CertainTeed vinyl siding. Avoid attaching panels so tightly that they cannot self-adjust for changes in temperature and wind.Full Answer >
Vinyl flooring is an affordable option for remodeling a kitchen, bathroom or laundry room, and with some careful planning, can be installed in under a day with beautiful results. The process is made simple by taking accurate measurements, removing the old flooring and filling any cracks or holes, then removing base molding and installing your new vinyl material. After trimming to fit, apply adhesive and let dry under heavy pressure to ensure no air is trapped between the subfloor and the vinyl.Full Answer >
