<P>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 by a strong alkaline solution. <I>Geopolymers as Sustainable Surface Concrete Repair Materials </I>offers readers insights into the synthesis, properties, benefits and applications of geopolymer-based materials for concrete repair.</P><P></P><P>¿ Discusses manufacturing and design methods of geopolymer-based materials</P><P>¿ Assesses mechanical strength and durability of geopolymer-based materials under different aggressive environmental conditions</P><P>¿ Characterizes the microstructure of these materials using XRD, SEM, EDX
