Description of High Alumina Cement

High alumina cement (formerly known as bauxite cement) is a hydraulic cementitious material with aluminate as the main mineral component, which is prepared by bauxite and lime in a certain proportion, calcined and ground, also known as aluminate cement. It exhibits exceptional refractory properties, including high-temperature resistance, excellent thermal shock resistance, and low shrinkage at elevated temperatures. This cement is specifically designed for applications in high-temperature environments such as furnace linings, kiln linings, and other refractory installations. It offers rapid setting and hardening, achieving high early strength, and demonstrates good resistance to chemical attack, making it suitable for acidic environments.

Advantages of High Alumina Cement

Large Heat of Hydration

Early cement hardening releases a lot of heat. Compared with Portland cement of the same grade, it can release 70-80% of the total heat of hydration in only one day. Due to several heat releases, it is suitable for concrete works with low-temperature curing. As the best supplier in China, Kerui can provide customers with the highest quality products.

Strong Resistance to Sulfate Erosion

The cement stone structure of high alumina cement is dense, the main component is low calcium aluminate, and the content of calcium oxide is very small. During the hydration process, free calcium hydroxide is not precipitated but aluminum hydroxide gel is formed. A protective film is formed on the particle surface.

Good High-Temperature Resistance

It will always maintain a solid state in a high-temperature environment, and the strength of the cement will not change. High alumina cement can be used as a cementing material for heat-resistant concrete and configured into heat-resistant concrete. Welcome to visit Kerui factory to get free quotation.

Early Strength Characteristics

Its early strength increase rate is far higher than that of rapid hardening Portland cement, which is suitable for emergency repair projects, but its strength will decrease later, and its use in structural engineering is limited. Kerui will provide you with professional solutions and high-quality products.

Application of High Alumina Cement

Construction Industry

High alumina refractory cement is often used in the production of refractory components in the construction industry, such as refractory bricks, refractory boards, refractory castables, etc. It can be used in the flue, furnace, heat treatment furnace, and other parts of the building to provide high-temperature resistance.

Metallurgical Industry

High-alumina refractory cement is often used in high-temperature equipment in the metallurgical industry, such as blast furnaces, converters, electric furnaces, etc. It can be used as a lining material to protect equipment structures from damage caused by high temperatures and chemical attacks.

Petrochemical Industry

In the petrochemical industry, high-alumina refractory cement is widely used in the lining and protective layer of high-temperature equipment such as oil refining units, chemical furnaces and reactors. It can withstand the high temperature and corrosiveness of petroleum products and chemicals.

Power Industry

High-alumina refractory cement is used in the power industry for the maintenance and protection of high-temperature equipment such as electric furnaces, boilers, and chimneys. It can withstand high-temperature combustion and flue gas corrosion, prolonging the service life of the equipment.

Glass Industry

In the glass industry, high-alumina refractory cement is often used as the inner lining and protective layer of glass furnaces, which can withstand the impact and corrosion of high-temperature glass liquid. It has strong corrosion resistance, increases the service life of the product and reduces production costs.

Iron and Steel Industry

In the steel industry, high-aluminum refractory cement is widely used in the lining of high-temperature industrial furnaces such as iron-making furnaces, converters, electric furnaces and coal-fired furnaces to withstand corrosion and erosion at high temperatures. It can effectively protect the walls of industrial furnaces.
