Correlation between Mix Design Study and Flexural Strength of Kaolin Coated Lumber Wood via Geopolymer Technology

Abstract:

Kaolin, an abundantly available material that mainly contains alumina and silica is now being used in geopolymer system. Kaolin based geopolymer has been proven to acquire remarkable thermal resistance, chemical resistance, and mechanical properties. Geopolymer materials have become the new favorite, especially for the carbon conscious end users as a potential replacement for widely used Ordinary Portland Cement (OPC). This works shares the effect of various mix designs, especially in terms of altering the solid/liquid ratio, sodium silicate/sodium chloride ratio and sodium chloride molarity on the flexural properties of kaolin coated lumber woods via geopolymer technology.
