Could someone tell me the major hydraulic reactive components in Portland Cement and also the undesirable by-product during the cement hydration reaction? Thanks.
Useful nucleus said:I believe alite (and to some extent belite) are the majot reacive phases in portland cement.
See: http://en.wikipedia.org/wiki/Alite
Regarding the other question, "undesirable" in what sense? For every application there is a corresponding undesirable byproduct.
Portland Cement is a type of hydraulic cement that is made by heating a mixture of limestone, clay, and other minerals in a kiln at high temperatures. It is a key ingredient in concrete, mortar, and other construction materials.
The hydraulic reactive components in Portland Cement are tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite. These compounds react with water to form a strong, durable binder that holds the cement and aggregates together.
The by-products of Portland Cement production include carbon dioxide, which is released during the heating process, and various particulate matter such as fly ash and silica fume. These by-products can be used in the production of other materials or disposed of in an environmentally responsible manner.
Portland Cement differs from other types of cement, such as lime or gypsum cement, in its composition and production process. It contains specific proportions of the hydraulic reactive components mentioned earlier, and is produced in a kiln at much higher temperatures than other types of cement.
The main properties of Portland Cement include high compressive strength, low shrinkage, and good durability. It also has a relatively fast setting time, making it suitable for a wide range of construction applications. However, it is important to use it properly and in the correct mixture to achieve the desired results.
