The density of cement can be anywhere from 62 to 81 pounds per cubic foot, depending on the type of cement. General purpose cement, for example, can have a density up to 81 pounds per cubic foot.Know More
There is another type of cement called builder's cement, which can have a density of anywhere from 62 to 78 pounds per cubic foot. Bulk density is not important for cement because, when thrown in water, the liquid fills in the spaces in between the particles where the air would normally be.
General purpose cement and builder's cement have different relative density ranges because they are fundamentally different kinds of cement. General purpose cement, also sometimes referred to as GP cement, is considered straight cement, made from cement clinker, gypsum and limestone. This type of cement is used in many different settings for construction of buildings and various other structures. Builder's cement, which is also sometimes referred to as general purpose blended cement, is different from regular general purpose cement because it contains a nominal mass of fly ash. This type of cement is known to maintain its strength for a longer period of time with improved workability and a lower carbon footprint.Learn more about Building Materials
Tricalcium silicate, also called alite, is one of the most abundant compounds found in cement and has the chemical formula Ca3SiO4. Its shorthand formula is C3S. Another abundant compound in cement is dicalcium silicate, which has the formula Ca2SiO5, or C2S in shorthand.Full Answer >
The typical ratio to mix cement is approximately 10 to 15 percent cement, 60 to 75 percent aggregate, and 15 to 29 percent water. In many concrete mixes, entrained air may take up another 5 to 8 percent.Full Answer >
Cut cement board by marking the cut, running a utility knife along the mark to cut the mesh overlay and snapping the board backwards to break it along the sliced line. Turn the board over, and cut the mesh on the other side at the break to complete the process.Full Answer >
In general construction use, there are 11 different types of cement, such as quick-setting, rapid-hardening and low-heat cement. Each type of cement is composed of different materials, and has markedly different uses, ranging from concrete that is aesthetically pleasing as flooring to concrete that can withstand high levels of acidity.Full Answer >
