Abstract

In the 21st century, humanity faces increasing concerns about climate change and natural hazards such as earthquake earthquakes and floods that induce deaths, homelessness and economic loss due to poor performance of civil infrastructure, particularly in ODA-eligible countries like Turkey, where the majority of infrastructures are mainly made of concrete. Therefore, it is also very important to ensure infrastructural assets are free from structural damage and are made up of environmentally friendly materials with long-term durability performance. The current project explores the development and use of a novel ductile, resilient composite material, improving the safety and resilience of civil infrastructures and reducing their repair and maintenance costs. For that purposes, nano boron nitride with two-dimensional layered structure has incorporated into sustainable engineered cementitious composites (ECC) to reinforce/modify their properties and performances. Then, flexural strength, compressive strength, and ultrasonic pulse velocity experiments were conducted on the prepared composites. One of the main objectives of this project is also to provide an in-depth understanding of the cracking characteristics and fracture behaviour of the samples in the light of micro-structural analysis obtained by using Scanning Electron Microscopy (SEM), X-Ray Diffraction method, and fractal theory. The investigation into the characteristics of these damages through systematic experimental and numerical analyses, will help better tailor and design nano modified engineered cementitious composites with desirable engineering properties, which would further promote the usage of this innovative composite in structural applications. reinforced concrete (FRC) [2].
