Alumina cement is a type of hydraulic cement that is made from bauxite and limestone. It is known for its high strength, durability, and resistance to chemical corrosion. This article will define and explain the meaning of alumina cement, its origin, associations, synonyms, antonyms, and root words.
Definitions
Alumina cement can be defined as a type of cement that is made from calcined bauxite and limestone. It is also known as calcium aluminate cement (CAC) or high alumina cement (HAC). Alumina cement is a hydraulic cement that hardens rapidly and is used in a wide range of applications such as refractory castables, precast concrete products, and sewer pipes.
Origin
Alumina cement was first developed in the early 1900s by French scientist Jules Bied. He discovered that a mixture of bauxite and limestone could be heated to produce a cement that had high strength and durability. The first commercial production of alumina cement began in France in 1908 and it quickly spread to other countries.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, alumina cement is defined as “a hydraulic cement made from bauxite and limestone and having a high alumina content”. The Oxford English dictionary defines it as “a type of cement made from bauxite and limestone, which is used for its high strength and durability”.
Associations
Alumina cement is commonly associated with the construction industry and is used in a wide range of applications such as refractory castables, precast concrete products, and sewer pipes. It is also used in the production of high-temperature ceramics, such as those used in the aerospace industry.
Synonyms
The synonyms of alumina cement include calcium aluminate cement (CAC), high alumina cement (HAC), and refractory cement.
Antonyms
There are no direct antonyms of alumina cement, as it is a unique type of cement that has specific properties and uses.
The same root words
The root words of alumina cement are alumina and cement. Alumina is a white or grayish-white, hard, and brittle mineral that is the chief ore of aluminum. Cement is a material that is used to bind other materials together and is made from a mixture of limestone, clay, and other materials.
