ABSTRACT

This study explores the integration of recycled materials, including TiO2-infused cement and cut-up plastic bottles, into cementitious mortars to advance sustainable infrastructure development. Through a series of thorough tests conducted after a 28-day curing period using the Benkelman beam method, the research assesses the mechanical properties and performance enhancements of these mortars. The findings aim to contribute to smoother roads, increased pavement durability, and improved pothole filling techniques, all while promoting eco-friendly practices in construction.

1. INTRODUCTION

   This project delves into the intricate domain of construction materials, focusing on pivotal components like cement, water, waste plastic bottles, fly ash, and the Benkelman beam apparatus. Cement, a cornerstone material, binds aggregates to form concrete, providing strength and durability, yet its production poses environmental challenges, prompting the need for sustainable practices. Similarly, waste plastic bottles present significant environmental issues, necessitating comprehensive strategies for reduction, recycling, and sustainable alternatives to address pollution and resource depletion. Through comprehensive analyses and testing methodologies, this study aims to illuminate the properties, applications, and sustainable practices associated with these materials, contributing to the discourse on sustainable construction practices and infrastructure management.

   Basic tests on various materials including cement, fine aggregate, coarse aggregate, concrete, and cement mortar are indispensable for evaluating their quality, properties, and suitability for construction applications. These tests ensure compliance with standards and specifications while addressing crucial aspects like

   particle size distribution, solidification time, and load-bearing capacity. Water absorption assessments offer insights into durability and material suitability, aiding in material selection and structural design. Proactive management strategies for potholes and the utilization of fly ash as a sustainable additive further enhance concrete performance and sustainability, underscoring the project’s commitment to advancing eco-friendly construction practices.

   Waste Plastics for Eco-friendly & Sustainable Road Construction in Bangladesh (Shafiq Alam,2008) have suggested that Waste plastics are environmental nuisance, prospective use of which would help to improve our road network as well as the environment. Advanced cold patching materials (CPMs) for asphalt pavement pothole rehabilitation (Tao Wang,2022) advanced CPMs for more effective pothole repair of asphalt pavement in cold and wet weather.

2. Test Conducted

Compression test: The compression test assesses a material’s ability to withstand compressive loads by gradually applying force to cylindrical or cubic specimens until failure occurs. Its primary outcome, compressive strength, indicates the maximum load the material can withstand. This data is crucial for structural design, quality assurance, and research on material behavior under stress. Additionally, the test reveals elasticity, deformation characteristics, and failure modes, aiding in suitability assessments for engineering applications.

The Benkelman beam:- A popular instrument for evaluating deflection of the pavements after the 28 days of concrete pouring. It gauges how flexible pavements deflect under wheel loads in motion. It is quite useful for evaluating pavement condition and identifying maintenance requirements due to its precision and simplicity. The Benkelman beam helps locate trouble spots, like rutting and cracking, by measuring pavement deflection. This enables prompt repairs and increased road safety.

1. RESULTS AND DISCUSSION

   Preparation of Concrete Cubes for Compressive Strength Test Concrete cubes were meticulously prepared to conduct strength analyses among various Nano Material Concretes. The constituents included Ordinary Portland Cement (OPC), Fine Aggregate, Coarse Aggregate, and Water, along with different percentages of Nano Materials like Titanium Dioxide (TiO2). These cubes were then subjected to compressive strength testing under varied conditions, including Room Temperature, Low Temperature, and High Temperature.

   In the presented table, diverse Nano Materials such as Titanium Dioxide (TiO2) were employed as partial replacements for cement at varying percentages to fabricate concrete cubes. The objective was to evaluate their compressive strength at Room Temperature. Notably, the compressive strength of Ordinary Portland Cement (OPC) concrete was measured at

   29.70 N/mm2 after 28 days at Room Temperature.
