Effect of Precursor Combination and Elevated Temperatures on the Microstructure of Alkali-Activated Binder
Publication details: Thane ACC LTD 2019Edition: Vol.93(10), OctDescription: 34-43pSubject(s): Online resources: In: Indian Concrete JournalSummary: Alkali-activated binders (AAB) are a new class of construction materials based on polymerization chemistry and are known to offer properties comparable to Portland Cement (PC) with a lower carbon footprint. The final performance of AAB is governed by the type and chemical composition of its raw materials, which significantly influences its microstructure. Understanding of the microstructural variations provides an estimate and reasoning for the specimen-level performance of AAB. The present study evaluates the effect of varying precursor proportion and high-temperatures on the microstructure of AAB pastes. Addition of slag at an optimum proportion enhances the high-temperature performance of AAB paste.| Item type | Current library | Status | Barcode | |
