Microstructural Evolution and Mechanical Performance of Ambient-Cured Fly Ash–Metakaolin Inorganic Polymer Composites Activated by Anhydrous Sodium Silicate PowderBy Ishant Dahat, Bhushan H. Shinde
Abstract: Inorganic geopolymer networks offer a low-carbon and sustainable solution to traditional binder systems through the alkali-activation of industrials-grade aluminosilicate material. The present paper focuses on the microstructure development and the mechanical performance of the ambient-cured fly ash – metakaolin inorganic polymer composite activated with solid anhydrous sodium silicate powder. Five inorganic polymer binder combinations were formulated by replacing fly ash with metakaolin at mass fractions of 0%, 10%, 20%, 30%, …

Design of a Geopolymer Based on Fly Ash and Metakaolin with a Solid, Liquid, and Powdered Alkaline Activator at High TemperaturesBy Ishant Dahat, Bhushan H. Shinde
Abstract: In this work, the fresh and hardened properties of geopolymer concrete activated using solid, liquid, and powder alkaline activator systems, including fly ash and different amounts of metakaolin, are examined. Compressive and flexural strengths were assessed at 7 and 28 days in accordance with IS 516 (1959). Workability was evaluated using a slump test in accordance with IS 1199 (Part 2): 2018. At an ideal replacement level of 30%, the …
