Microfibrillated Cellulose vs. Fumed silica: characteristics and applications

By Synnøve Holtan 13. December 2016

Microfibrillated cellulose (MFC) and fumed silica are both used for controlling the rheology of liquid systems, such as thixotropy and stability, and may be used within the same field of applications giving similar properties. However, there are also profound differences between the two. For example, where MFC is a natural product derived from cellulose-based raw materials, the native hydrophilic fumed silica is an amorphous, colloidal silicon dioxide prepared by a flame hydrolysis process. So why can two such, at first glance, different products be used in similar applications? In this blog post, I will dig more into detail about the two multifunctional additives, and discuss how their similarities and differences may affect application properties.

How MFC can improve concrete rheology

By Tania Risson 2. August 2016

Concrete products are a complex mixture of chemicals, fines, and heavy particles. It's always challenging to control the stability, flow and strength of it. Many admixtures have been created to overcome these challenges, often containing synthetically derived performance additives.
