Development of expanded clay as an internally curing concrete aggregate

Abstract

Internal curing is an emerging technology in cement concrete industry to replace the conventional curing process by supplying excess water throughout the concrete mixture. Internally curing will outperform in road construction industry than conventional curing methods due to its convenience of use in harsh environmental conditions. The research mainly focuses on finding a suitable internal curing concrete aggregate (ICCA) in Sri Lanka to use in cement concrete applications. The study presents a summary of internally curing concrete aggregate types available globally. Expansive clay available in the selected locations were able to process and develop as internal curing aggregates.
