The progressive deterioration of concrete surface structures is a major concern in construction engineering that requires precise repairing. While a number of repair materials have been developed, geopolymer mortars have been identified as potentially superior and environmentally friendly high-performance construction materials, as they are synthesized by selectively combining waste materials containing alumina and silica compounds which are further activated via strong alkaline solution. This book offers readers insight into the synthesis, properties, benefits, and applications of geopolymer-based materials for concrete repair. • Discusses manufacturing and design methods • Assesses mechanical strength and durability under different aggressive environments • Characterizes the microstructure of these materials via XRD, SEM, EDX, TGA, DTG and FTIR measurements • Describes application as surface repair materials • Compares environmental and cost benefits against those of traditional OPC and commercial repair materials This book is written for researchers and professional engineers working with concrete materials, including civil and materials engineers.

Geopolymer mortars have been identified as potentially superior and environmentally friendly high-performance construction materials. This book offers readers insight into the synthesis, properties, benefits, and applications of geopolymer-based materials for concrete repair.
