Recyclable Wastes as Internal Curing Materials to Improve High-Performance Concrete's Sustainability, and Durability: An Overview

Abstract

This study discusses the researchers' experiences with regard to the use of sustainable materials (waste materials and recycling materials) as internal curing materials during the development process for high-performance concrete (HPC). Generally, the use of waste materials as internal curing materials to enhance interior curing reduces the self-desiccation that occurs in cement paste concrete and can thus reduce the risks of the cracks that may develop as a result of modern concrete hardening. This research also examines high-performance concrete behaviours, including characteristics such as density, compressive strength, splitting tensile strength, and flexural strength to examine internal curing efficiency. This appears to be more effective with age progression in terms of compressive strength and splitting tensile strength. The results of the research show that the use of waste materials as internal curing agents not only enhances the properties of concrete but also offers a renewable method for reducing the amount of waste globally.
