The Effect of Sodium and Magnesium Sulfate on Physico-Mechanical and Microstructural Properties of Kaolin and Ceramic Powder-Based Geopolymer Mortar
TL;DR: In this paper , the use of natural kaolin and raw ceramic powder as the main precursors was adopted to provide a greener route for this binding system, and the activation process was performed by using solid potassium hydroxide in conjunction with sodium and magnesium sulfate, which are naturally available, to produce geopolymers.
