  • Cemfast RS

    CEMFAST RS excels through its rapid setting and thereby enables safe processing with improved strength development, even at low temperatures. A good early strength value and a controlled setting process are the results of a balanced product design.

    CEMFAST RS is therefore ideally suited to all applications in which early setting is necessary. 

    CEMFAST RS was designed specifically for binary binder systems with Portland cement. In comparison with other Calcium Aluminate Cements, it offers lower dosing with comparable effectiveness. Yet despite this, CEMFAST RS still provides developers with the necessary scope and freedom to exert individual influence on the properties of the end products through use of various additives such as retarders, accelerators, plasticizers or even calcium sulfates.

    Typical fields of application include fast 

    • very fast-setting concretes for landscaping and garden construction applications 
    • quick repair mortar 

    CEMFAST RS 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.
