Silica Fume in Geopolymers: A Comprehensive Review of Its Effects on Properties

Description

This book provides a comprehensive review of past studies that have investigated the effects of Silica Fume (SF) on the properties of geopolymers in its three different forms: as an additive to the precursor, as part of an activator, or as a foaming agent. By analyzing previous studies, this book aims to provide a clear understanding of the positive and negative effects of recycling SF into various geopolymer types. It is a valuable resource for researchers, academics, and professionals working in the field of geopolymer technology and cementitious materials.
