High calcium Fly Ash geopolymer stabilized lateritic soil and Granulated Blast Furnace Slag blends as a pavement base material.
Itthikorn Phummiphan,Suksun Horpibulsuk,Runglawan Rachan,Arul Arulrajah,Shui-Long Shen,Prinya Chindaprasirt +5 more
TL;DR: Granulated Blast Furnace Slag, which is traditionally considered as a waste material, is used as a replacement and partially reactive material in FA geopolymer pavement applications, and microstructural analysis indicated the coexistence of Calcium Silicate Hydrate (CSH) and Sodium Alumino Silicates Hydrate products in FA geopolitical stabilized LS/GBFS blends.

Mechanism of geopolymerization and factors influencing its development: a review
Divya Khale,Rubina Chaudhary +1 more
TL;DR: In this paper, the authors present the work carried out on the chemical reaction, the source materials, and the factor affecting geopolymerization, and demonstrate that certain mix compositions and reaction conditions such as Al2O3/SiO2, alkali concentration, curing temperature with curing time, water/solid ratio and pH significantly influences the formation and properties of a geopolymers.
