An Experimental Study on Mechanical Properties of Concrete by Using Various Types of Coarse Aggregates of Different Quarries

Abstract

This research study aims to conduct a comprehensive investigation of the mechanical properties of concrete in the specific context of Pakistan. It will utilize a variety of aggregate sources, including Sakhi Sarwar crush, Margallah crush, Sargodha crush, and Quetta crush. The primary objectives of the study encompass a thorough analysis of the physical and mechanical characteristics of these aggregates. Additionally, the study seeks to investigate how the choice of aggregate type affects the mechanical properties of concrete and how different mix designs impact the performance of the concrete. Ultimately, the research aims to identify the optimal mix design for each aggregate source and conduct a comparative evaluation of the resulting mechanical properties. The importance of this study lies in its potential to make a significant contribution to the construction industry in Pakistan. The findings are expected to offer valuable insights that can inform decisions regarding aggregate selection and enhance the optimization of concrete mix designs, there by leading to improved concrete performance, durability, and advancements in infrastructure development. Furthermore, this research aligns with sustainable development goals by promoting responsible consumption and production, sustainable urban development, climate action, and sustainable land use practices. It's worth noting that this study has certain limitations, such as its focus on a limited number of aggregate sources and its reliance on laboratory-based experiments. However, this research serves as a foundation for future studies and emphasizes the importance of collaboration, knowledge sharing, and ongoing research efforts to improve construction practices in Pakistan.
