What is Refractory High Alumina Cement?<\/h2>\n

Refractory high alumina cement is made by grinding alumina and calcareous material such as lime through sintering or fusing.<\/p>\n

Also known as calcium aluminum cement, it is a common and popular refractory material because of its benefits and refractory cement uses.<\/p>\n

So in this article, we reveal why it is the best refractory material.<\/strong><\/p>\n

<\/p>\n

Where is Alumina Refractory Cement from?<\/h2>\n

In general, a cement maker in the United Kingdom named Lafarge developed alumina cement in 1925.<\/p>\n

However, they found that high alumina concrete could withstand chemical hazards mainly in marine construction. Years passed and engineers found other qualities such as its easy production and rapid strength gain.<\/p>\n

How is High Alumina Cement Made?<\/strong><\/span><\/h2>\n

Basically, manufacturing alumina refractory cement<\/strong> differs from the production of ordinary concrete. This is because it essentially uses bauxite and lime as the raw material.<\/p>\n

They are mixed following the set amounts which will be grounded into 100mm fragments. Then, the fragments enter a kiln to heat up to its fusion point (1600\u00b0C).<\/p>\n

The molten product is then transferred down a steel plate to cool in a rotary kiln. Afterward, it is finely grounded into tube mills until the product is at 2250cm\u00b2\/gram.<\/p>\n

      Uses of High Alumina Cement Concrete for Refractory<\/h2>\n

      Generally, this refractory product<\/strong> is widely used in sewer infrastructure<\/a> and marine construction.<\/p>\n

      Besides, high alumina cement is used because furnaces, boilers, kilns, and chimneys need refractories. This is due to its strength to withstand very high temperatures with proven durability.<\/p>\n

      Benefits of Refractory High Alumina Cement<\/strong><\/span><\/h2>\n

      High alumina refractory cement concrete<\/strong> has many advantages due to its large-scale properties.<\/p>\n

      Furthermore, its heat resistance is useful for industries dealing with high temperatures even direct fire.<\/p>\n

      Moreover, it has high compressive strength and is very reactive. Also worth mentioning is its low frost action as there is more heat evolved during the setting process.<\/p>\n

      Know your Refractory Materials<\/h2>\n
      \n

      Learning about different refractory materials benefits your project<\/span><\/h3>\n<\/blockquote>\n

      Although this refractory cement<\/strong> has many good qualities, it is important to note that it also has its disadvantages.<\/p>\n

      As previously mentioned, the cement fineness is not less than 2250cm\u00b2\/gram which is very fine. Thus, workers who handle it may have it enter their eyes, mouth, or inhaled.<\/p>\n

      Therefore, you must consult a trusted refractory contractor<\/strong>. So you know the refractory options before starting your refractory installation.<\/p>\n
