Method for Determining Fracture Energy of a Polypropylene Coarse Lightweight Aggregate Concrete Beam Using Digital Image Correlation
Abstract
This study aimed to propose a method for determining the fracture behavior of sand-coated polypropylene coarse aggregate lightweight concrete (PP-LWAC). To understand the fracture response, an experimental investigation is carried out on 36 beam specimens and PP-LWAC is prepared using sand-coated PP aggregate based on previous study. The mix proportion is designed to match with three different specified compressive strengths. The Work of Fracture Method (WFM) and Size Effect Method (SEM) is used to define the fracture parameters, proposing the relationship between the fracture parameters and the compressive strength. Additionally, the crack mechanism is studied using the Digital Image Correlation (DIC) method.
