Cement products include a variety of types such as Portland cement, which is the most common used in construction, and blended cements like fly ash or slag cement that enhance specific properties. Other products include masonry cement, which is used for mortar, and oil well cement, designed for use in oil drilling. Additionally, specialty cements like rapid-setting cement and white cement cater to specific applications in construction and aesthetic purposes.
http://simscience.org/cracks/advanced/concrete2.html A common mistake people make is to use the words cement and concrete interchangably. It is important to remember that cement is only a component of concrete and concrete is the structural material. The cement used in concrete is not used as a building material because it would be too expensive and not as strong as concrete. So when you see a parking garage, a driveway, a sidewalk or a road remember it is made of concrete, not cement. And, by the way, that funny looking truck is a concrete mixer, not a cement mixer! But, if cement is not concrete, then what is it? Cement is a general name for a material that binds other materials together. Yes, it is another name for glue. There are many materials which we would classify as cements and they are usually identified with certain uses, and can produce different types of "concrete". The type of cement used to make the riding surface of some of our roads (blacktop!) is called asphalt cement. It is a petroleum bi-product, and it binds rock into the road material we call asphaltic concrete.
Cement skin is commonly referred to as "cement burn" or "concrete burn." It occurs when the skin comes into contact with wet cement, leading to chemical burns and irritation due to the alkaline nature of the material. Proper protective gear, such as gloves and long sleeves, is essential to prevent this condition when working with cement.
when water is added to the cement,cement volume decreases due to removal of air from cement particles. this reduction in cement volume is the bulkage

To hydrate a 50 kg bag of cement, approximately 25-30% of the cement weight is typically required in water, meaning around 12.5 to 15 kg of water is needed. This amount can vary based on factors such as the type of cement, environmental conditions, and specific mix designs. It's essential to follow guidelines and adjust based on the desired workability and strength of the final product.
If it is a product of James Hardie, no. It is primarily a Portland Cement and cellulose product.
It can be both, depending on packaging. By "cement" you're talking plain ol' Portland Cement for making concrete, correct? In bulk it's a commodity; in 94-pound bags it's a product.
petroleum cement and nickel
Cement bricks are made of Cement- it's in the name.
Kerosene, a petroleum product will not interact chemically with Portland cement - water will.
Cement typically contains minerals like limestone, clay, silica, and gypsum. These minerals are essential for binding and hardening the mixture to form the final cement product.

Asbestos-cement wallboard looks like any other cement board product. Only analysis by a qualified lab can tell the difference.

um, they'll be hard. duh. ----------------- concrete is made of cement, sand and aggregate (stone, gravel, etc) so its a redundant question. Cement by itself is not very strong, its is a binder used to make concrete. In some cases sand is also the aggregate (QuickCrete is one product name)
