High Alumina Cement | The Construction Civil

What is Calcium Aluminate Cement. Calcium Aluminate Cement is a hydraulic binder with normal setting and rapid hardening obtained by finely grinding the resulting product of the combustion mixture of limestone and bauxite. Bauxite is a hydrated aluminum trioxide (Al2O3. NH2O) that contains impurities of silicon dioxide and iron trioxide.

Advantages of High Alumina Cement

May 01, 1982· Calcium aluminate cement concretes are not rapid setting. They are, however, rapid hardening; that is, they will develop as much strength in 24 hours as Portland cement concrete will achieve in 28 days. Calcium aluminate cement concretes should be cured for at least 24 hours, using a water spray or fog, ponding, wet burlap or a curing membrane.

High Alumina Cement

Alumina Ratio (AR) The alumina ratio is defined as: AR=(Al 2 O 3 /(Fe 2 O 3) This determines the potential relative proportions of aluminate and ferrite phases in the clinker. An increase in clinker AR (also sometimes written as A/F) means there will be proportionally more aluminate …
