The Optimizing High-Performance Concrete using SCMs: A Review of Mechanical and Durability Properties

Abstract

This conference paper from Capital University of Science and Technology, Islamabad, explores the optimization of High-Performance Concrete (HPC) through the integration of Supplementary Cementitious Materials (SCMs) to align with sustainability goals. Emphasizing the development of HPC blends with exceptional mechanical properties, the study highlights the importance of locally sourced materials. HPC, designed for superior strength and durability, has evolved beyond very high strength over the last 15 years. The literature review underscores the holistic approach to durability in HPC, focusing on resistance to weathering and chemical attacks. Structural properties like compressive, tensile, and flexural strengths are pivotal for robustness. SCMs, including fly ash, play a crucial role by initiating pozzolanic reactions, enhancing microstructure, and increasing overall strength. The methodology employs a strategic mix proportioning process, considering factors like water-to-cement ratio and aggregate gradation. Mechanical and durability tests, following ASTM codes, assess properties like compressive strength, tensile strength, permeability, and freeze-thaw resistance.
