Analysis of Workability and Mechanical Properties of Alkali-Activated Recycled Aggregate Fiber Concrete

Abstract

Alkali-activated recycled aggregate fiber concrete is an innovative material that combines alkali activation technology, recycled aggregates, and fiber reinforcement. This paper systematically analyzes the workability and mechanical properties of this concrete. Experimental studies assessed the workability of alkali-activated recycled aggregate fiber concrete, including its flowability and workability, and explored how these characteristics impact construction and use. Additionally, a detailed analysis of the concrete's mechanical properties, such as compressive strength, tensile strength, and flexural strength, was conducted. The results indicate that alkali-activated recycled aggregate fiber concrete maintains good workability while significantly enhancing mechanical properties, with excellent crack resistance and toughness. The paper also discusses the key factors affecting these properties and provides an outlook on future research directions and practical applications.
