High-Temperature, Drying Shrinkage, and Environmental Impact Assessment of Alkali-Activated Concrete

Alkali-activated Concrete (AAC) is a potential substitute for traditional Portland cement concrete. However, uncertainties regarding its chemistry and a lack of information on long-term practical performance restrict it to precast applications. Several studies have addressed the chemistry and mechanical properties of AAC. So, this book emphasizes the long-term characterization of AAC, especially under the following categories: High-temperature exposure; Drying shrinkage; and Environmental impact assessment.The performance of AAC under each of these categories is significantly enhanced, compared to traditional Portland cement. With the recent need for sustainable construction and the increasing number of standards for AAC, it can soon find wider practical usage as a partial or complete substitute for Portland cement.This book compiles the relevant findings on AAC in the long term to showcase its advantages over traditional Portland cement. Given the uncertainties associated with the chemistry, the challenges, practical recommendations, and future scope of research are also highlighted.
