Introduction,lymer and geopolymerization is presented. Subsequently, two crucial constituents of MKG, namely metakaolin and alkali activator, are introduced. Furthermore, notable distinctions between geopolymer and ordinary Portland cement (OPC) are highlighted. Lastly, this chapter discusses the various applica

Geopolymerization of MKG,apter, vacuum dehydration and nuclear magnetic resonance analysis were conducted to investigate the geopolymerization process of fresh MKG paste. Four distinct stages of geopolymerization were identified, including dissolution, short-ranged polymerization, structural rearrangement, and long-ranged c

Composition-Dependent Mechanical Performance of MKG,tional design of MKG. This chapter investigates the elastic and creep behavior of MKG. The elastic stress–strain behaviors of MKG are measured under uniaxial compression, and the basic elastic parameters (including Young’s, bulk, and shear moduli and Poisson’s ratio) are evaluated. The binder phase

Drying Shrinkage of MKG,gates the drying shrinkage of MKG with different initial water/solid ratios and pore structures. Experiments using mini-bar shrinkage techniques reveal a two-stage behavior in the relationship between drying shrinkage and water loss of MKG. Although the initial water/solid ratio affects the crucial

Sulfate Corrosion of MKG,the impact of the Si/Al ratio, a significant compositional parameter of MKG, on its resilience when exposed to sodium and magnesium sulfate solutions. Additionally, this study thoroughly investigates the stability of MKG mortars’ chemical, physical, and mechanical properties over the course of 180 d

Aggregate Influence on MKG Concrete,Experimental investigations were carried out to examine the influence of coarse aggregate size on both the mechanical properties and microstructure of MKG concrete. Additionally, the impact of coarse aggregate size on the bond between Carbon Fiber-Reinforced Polymer (CFRP) and MKG concrete was inves
