[Construction Section 148]
SPECIAL CEMENT
The high standard of the construction industry in the concrete building materials, and hence to the cement binder make it necessary to cement with special chemical and physical properties. This is done by the grinded various substances such as metallurgicals andes, puzzolan, fly ash or lime stone in varying quantities.
CHARACTERISTICS
This cements with special characteristics influence the hydration rate, the so-called cement with low hydratation-warmth. Also affected is also the resistance to chemical substances, which is the so-called cement with high sulfate resistance.
Or, in some types of cement is also supported by the low effective alkali or by the workability and strength of cement influenced. Apart from normal gray cements is also white cements. These are of very little iron contained raw materials and manufactured primarily for construction materials like e.g. terrazzo, exposed concrete and plaster.
- White cement is not only suitable for preparations pale colored, but can be used with color pigments colorizing lighter gray than ordinary portland cement. This makes it particularly in the manufacturing colored terrazzo advantage.
- Thurament is a special cement from blast furnace slag, or smelting sand. It has a share in plaster.
