CEMFAST is an anthracite-brown, quick-setting and fast-hardening Calcium Aluminate Cement with high early strength values. This special performance is facilitated by matched mineralogy in connection with optimum granulometry. This offers clear advantages, particularly in the early phase of the setting process.
The compressive strength after 6 hours is up to 10% higher than with classic Istra 40 – without having to accept serious trade-offs during the remaining hardening process.
CEMFAST is therefore ideally suited to all applications in which the strength at the start of the setting process needs to be improved without compromising the final strength value. CEMFAST is also suitable for use with ternary binder systems with the objective of achieving fast ettringite formation.
Typical fields of application include fast, technically challenging systems:
- quick repair mortars
- repair systems for road construction applications
- anchor mortar for mining applications.
CEMFAST fulfills the requirements of EN 14647.
CEMFAST is part of a product range for specific applications in the field of construction chemistry. The following comparison provides an initial overview of the key properties of these aluminate cements for special applications.
