i.tech® ALI PRE is ground Calcium Sulfoaluminate clinker (CSA). i.tech® ALI PRE offers more flexibility as the binding time can be managed over a very wide time period. Even the strength development can be moulded very flexibly thanks to the mixing ratio with Portland cement and calcium sulphate.
The material was created to offer the refractory Customers high refractoriness parameter and followed by shorter than regular GÓRKAL 70F setting time. It is important to mention that the material is chemically pure cement.
White powder with the crystallographic form of rutile, non-toxic, non-flammable and chemically inactive. Surface treated with aluminium compounds (in amount of 3% as Al2O3) and modified with hydrophilic organic compounds.
Physico-chemical properties - Iron pigment MR 25 is natural pigment with good optical features. It is resistant to light, warm and neither its chemical nor physical status does change under the influence of humidity, alkalis or weak acids.
