Feature and Application Of Alumina Cement

Fast hard early strength, early strength growth fast, suitable for emergency repair engineering and early strength requirements of high engineering. The late strength of high alumina cement may decrease, especially in the humid and hot environment above 30℃, the strength will decline faster, and even cause the destruction of the structure. Therefore, the use of aluminum cement in structural engineering should be cautious.
Alumina cement hydration heat, and will be concentrated in the early release. It is suitable for construction in winter, not for mass concrete project and high temperature and humidity environment.
This series of refractory cement has good resistance to sulfate attack. The main component of alumina cement manufacturing is low calcium aluminate, free calcium oxide is very few, cement stone structure is relatively close. Therefore, it is applicable to the engineering required to resist sulfate erosion.
High alumina cement in contact with alkaline solution, even when the concrete aggregate contains a small amount of alkaline compounds, will cause erosion. So it can’t be used for projects that touch alkaline solutions.
Good heat resistance. Alumina cement manufacturing at high temperature will produce a solid reaction, sintering bonding instead of hydration bonding, so that high aluminum cement at high temperature can still maintain high strength.

It is mainly suitable for use in the environment of 5~35℃, in the refractory castable with a certain proportion of high temperature refractory cement, can make the refractory castable in the construction of rapid condensation, dense.

High alumina refractory cement has strong sulfate resistance. This series of refractory cement has a dense cementstone structure, the main component is low calcium aluminate, calcium oxide content is very little. It is suitable for engineering with high demand of resisting sulphate erosion.

This series of refractories has good heat resistance, and will always maintain the solid state under high temperature environment, and the strength of the cement will not change. However, the use of high alumina refractory cement is more demanding, because its early strength growth is fast, more suitable for use in the emergency rescue project, or the early strength of the project.

It is worth noting that, its alkali resistance is slightly weak, and alkaline solution contact will cause erosion, and the concrete aggregate contains a small amount of alkaline compounds will also cause erosion, so contact with the alkaline solution of the project, can not use high aluminum cement.

High Alumina Cement Feature

1. Early strength characteristics: its early strength improvement rate is much higher than that of fast hardening Portland cement, which is suitable for emergency repair projects, but the late strength will be reduced, so it is limited to use in structural engineering.

2. Hydration heat large, and concentrated in the early release: suitable for winter construction, can not be used in mass concrete works and high temperature humid environment of the project. Because of several kinds of exothermic, suitable for low temperature curing concrete works.

3. Strong resistance to sulfate: in the hydration process, free calcium hydroxide is not separated out, but aluminum hydroxide gel is formed, and a protective film is formed on the particle surface. The resistance to erosion was reduced during the later crystal transformation. Therefore, it is suitable for engineering with the requirement of resisting sulfate erosion.

4. High temperature resistance: high alumina cement can be used as the cementing material of the heat resistant concrete, configured into the heat resistant concrete.

5. Good heat resistance: because of the high temperature of the production of solid reaction, sintering bonding instead of hydration, so that high aluminum cement at high temperature can still maintain a high strength.
