What high alumina cement?
High alumina cement is obtained by fusing or sintering a mixture in suitable proportion of alumina and calcareous material and grinding the resultant product to a fine powder.Raw materials are limestone and bauxite.About 20% of strength is achieved in one day.
What is high alumina cement used for?
High Alumina Cement is an inorganic material that form a dense texture when it reacts with water and has a excellent refractory, quick hardening property and resistance to chemical attacks. This type of cement is produced by grinding clinkers formed by calcining bauxite and lime

What is the use of baxuite?
Bauxite is primarily used as the main source of aluminum production. It is processed to extract alumina (aluminum oxide), which is then refined to produce aluminum metal. Additionally, bauxite is utilized in the manufacture of refractory materials, cement, and as an abrasive in various industrial applications. Its high alumina content makes it valuable in these sectors.
Does alumina become conductive at high temperatures?
Alumina is a good electrical insulator; at high temperatures the resistivity is smaller than the resistivity at room temperature.
